Twilight is a young adult vampire novel written by author Stephenie Meyer, originally published in hardcover in 2005. It is the genesis of the Twilight series, and introduces seventeen-year-old Isabella "Bella" Swan who moves from Phoenix, Arizona to Forks, Washington and finds her life in danger when she falls in love with a vampire, Edward Cullen.
Isabella Swan, more commonly known as Bella, moves from sunny Phoenix, Arizona to rainy Forks, Washington to live with her father, Charlie, so that her mother, Renee, can travel with her new husband, Phil Dwyer, a "strictly minor league" baseball player. Even though she never had many friends in Phoenix, Bella quickly discovers she is the new subject of curiosity at her new school in Forks, where she is quickly befriended by several students. Much to her dismay, several boys in the school compete for shy Bella's attention.
While sitting next to Edward Cullen on her first day of school, he displays extreme tension. This leads Bella to believe that he dislikes her. However, his attitude towards her soon begins to change. He displays supernatural abilities while saving Bella from being hit by an out-of-control van about to crush her into another car. After seeing a dent on the side of the van in the shape of Edward's shoulder, she realizes the van hit him and that he seemed to be holding it away from her, keeping her safe. Bella confronts him afterwards about the strangeness of the situation, but he refuses to talk to her about it. As time passes, Bella and Edward are repeatedly attracted to one another, even though Edward desperately tries to stay away in order to keep her out of the danger that he will likely put her in.
Bella eventually learns from her friend Jacob Black of the Quileute (pronounced Quil-yoot) tribe and her own observations that Edward and his family are reformed vampires who substitute animal blood for human blood in their diet.
Edward and Bella fall deeply in love. Their foremost problem is Bella's "alluring scent", making it difficult for him to restrain himself from attacking her. However, despite this and Bella's strange knack for constantly landing herself in dangerous situations, they manage to stay together safely for a time.
The seemingly blissful state of affairs is thrown into chaos when another vampire coven sweeps into Forks and James, a tracker, sets his sights on Bella. Under the assumption that James has kidnapped her mother, Bella is lured to her former dance studio, where James attacks her. Edward, along with the rest of the Cullen family, rescues Bella before James can kill her.
The book ends with the two going to Bella's prom. Beneath the surface, tension remains as Bella wishes for Edward to turn her into a vampire and Edward refuses to do so. The reason for Edward's adamant decision not to turn Bella into a vampire is not yet revealed.

New Moon is a young adult romance novel by author Stephenie Meyer. This book, unlike the previous book in the series, is about losing true love. It is Meyer's second novel in the Twilight series. It was originally published in hardcover in 2006.
Isabella "Bella" Marie Swan is thrown an eighteenth birthday party by Alice and Edward Cullen, the vampire whom she loves, and the rest of their vampire family consisting of Carlisle, Emmett, Esme, Rosalie and Jasper. During the party Bella accidentally gets a paper cut, which leads to a violent and tense moment. Jasper, the newest member of the 'family' to try out the non-human diet, cannot contain himself at the sight and smell of her blood and makes a leap for Bella. Edward is forced to protect her, making him realize that keeping Bella close to the family puts her at risk. In the midst of this, a pivotal moment occurs during a conversation with Carlisle while cleaning her wounds. Bella is told that Edward believes that vampires are soulless creatures and that there is no better place for them if they die. It is made clear that Edward's relationship with her is a constant tug-of-war in his heart because he doesn't want to risk turning Bella into a creature who he believes is damned. Edward begins to withdraw himself emotionally, and later he and his family depart from Forks in an attempt to keep Bella safe. He unknowingly hurts Bella further by taking photos and memories from her possession that would prove his existence, in an attempt to make a clean break of their relationship.
Four months pass and Bella has become a "zombie"; existing but not really living. Charlie gets sick of it and tells her to snap out of it, threatening to send her back to live with her mother in Jacksonville, Florida. She listens to Charlie and goes to see a movie with her friend Jessica. After the movie finishes she sees some men that are similar to the stalkers she encountered the previous year. She begins to approach them, trying to see if they are the same men. She then hears Edward's voice in her head warning her to stay away from them, and wonders if she's on the verge of insanity. However, she thinks that her subconscious mind was giving her a "wish of fulfillment" with the idea that Edward cared if she lived or died. Thinking that the delusions are triggered by recklessness, she seeks other ways to trigger the delusions.
Jacob Black, the young Native American from Twilight, makes a reappearance in New Moon. Bella finds two motorcycles on the side of the road, thinking they are the perfect way to hear Edwards voice. However, they need work and she remembers that Jacob is a mechanic of sorts. She loads them onto her truck and offers Jacob one of them as payment if he can make them run. They become very close friends and Bella comes to depend on him, filling up the hole in her heart as best as she can with their friendship. Jacob is attracted romantically to Bella and although Bella knows this and tells him they are just friends, there is nothing uncomfortable about their closeness.
In the midst of their growing closeness, Jacob confides in Bella that something is going on at La Push reservation. Jacob confesses that he is afraid of Sam Uley, the leader of a group of older guys on the reservation. A friend of his had expressed fear of the group, went missing for days, and then resurfaced as a member of the gang. He has been acting strangely and Jacob believes they are up to no good. He is also frightened that he could be next on the list.
During an outing with Bella, Jacob becomes very ill and fevered. After this episode Bella finds that it is almost impossible to get in contact with Jacob, before finding out that he has reappeared as a follower of Sam Uley. Bella confronts him at his house and Jacob harshly tells her that he must stay away from her, refusing to explain why. However, after a fight ensues Jacob is clearly hurting and regretful, and sneaks into her room late at night to tell her that she knows exactly what is happening to Jacob, she just doesn't realize it. The only clue he gives her is a reminder of the legends that he told her when they first met.
Bella eventually recalls a story about werewolves and vampires and realizes that Jacob, and the rest of Sam Uley's gang, are indeed werewolves, and thus the enemies of her beloved Cullens. This presents a whole new set of problems for Jacob and Bella, because not only is there animosity between Jacob and Edward because of their mutual love for Bella, but they are also sworn enemies because of what they are. There is genuine potential for bloodshed and the possible death of either at the other's hands.
Things are further complicated by the return of Victoria. Victoria seeks to avenge her mate, the vicious tracker vampire James, whom Emmett and Jasper destroyed after James attempted to kill Bella. Rather than kill Edward, Victoria sees killing Edward's "mate" as a fair trade. She does not realize that Edward and his family have left Forks. It is up to Jacob and his pack to protect Bella from Victoria's revenge. Jacob and his pack then try to protect Bella and her father Charlie by encouraging them to spend most of their time in La Push.
Bella spends most of her time on First Beach. She soon gets frustrated and desperate to hear the voice of Edward, and thus jumps off a cliff, attempting cliff diving. When she hits the water she gets caught in a rip current and almost drowns. She hears Edward's voice pleading with her to try to fight the water, but she ignores it, thinking she will be dead soon. Her last thoughts before she almost dies are, "Goodbye, I love you," but Jacob saves her and informs her that one of Charlie's friends, Harry Clearwater, is in hospital suffering from a heart attack. Bella instantly regrets jumping off the cliff and feels sorry for her father. Bella then goes to Jacob's home where they rest, and she thinks of what would happen if Romeo (Edward) left Juliet (Bella) and Juliet ended up with Paris (Jacob), linking it to her own life.
Jacob's father, Billy, comes home and informs them that Harry passed away. Jacob then takes Bella home, where Bella sees Carlisle's car and thinks that the Cullens have come back to Forks. Jacob gets angry at Bella and leaves her to face the vampires by herself. Bella finds only Alice waiting for her. Bella rejoices in Alice returning but soon realizes that it's only temporary. Alice "saw" Bella jump off the cliff and thought that she was committing suicide. She did not see Jacob save her because, as she later finds out, she cannot see werewolves in her visions. Bella dismisses it but Alice is still curious as to why she jumped.
During Alice's stay, Jacob sees Bella and is still angry that she chose the "bloodsucker" over him. While he visits Edward calls, pretending to be Carlisle, and Jacob answers the phone. Edward asks Jacob where Charlie is and Jacob answers "at the funeral", meaning Harry Clearwater's funeral. Edward misinterprets this and thinks that it's Bella's funeral, and tries to commit suicide. After Alice realizes this, she and Bella leave to go to Volterra, Italy, where Edward is begging the Volturi, a "royal" vampire family, to kill him. His attempt falters because the Volturi think it is a "waste". Edward then tries to anger the Volturi into kill him by stepping into the sun where his skin will sparkle like diamonds and, potentially, reveal their existence.
Luckily, Bella stops Edward just before he steps into the sun. However, the Volturi still want to talk to them (Bella, Edward, and Alice). Relieved and shocked to see her alive and thinking these will be their last moments together, Edward shows affection toward Bella. She wonders why this is, as she thinks that Edward is no longer interested in her. They meet Aro, one of the Volturi leaders. He discusses Bella's future and says that she will need to become a vampire, due to the fact that they need to keep their existence a secret. Edward does not agree, but Alice shows Aro that Bella will become a vampire in the future, and he agrees to let them go.
Bella is overjoyed that Edward is back, and he explains that he only left in order to protect her. He tells her how hard it was to be apart from her, saying that it felt like "half of me was gone". Bella and Edward then go to Edward's family and they "vote" over Bella's mortality, stating their opinion on if she should become a part of their family and a vampire. All of them but Rosalie and Edward agree that she should be changed. Edward gets angry, but agrees that Bella should be changed after graduation, a few weeks away. Carlisle agrees to change her, due to his ability to maintain self control over blood. Bella would rather Edward change her, but will take what she can get. Edward is reluctant, but agrees only with the condition that Bella should marry him first. Bella is terrified, not wanting to end up like her mother and father, but considers it.
In the epilogue, Bella thinks back to her "pre-zombie" state and says that "it was as if the last seven months never happened". Jacob returns Bella's motorcycle in a vain attempt to get Charlie to ground her (being a policeman, Charlie doesn't want Bella to be using a motorcycle) and in turn keep Edward from seeing her. However, Jacob is unaware that Bella is already grounded by Charlie for her leaving him for three days without his permission. Charlie is even more furious with Bella but she knows that with Edward at her side, everything will be okay.

Eclipse is the third book in the Twilight Series by Stephenie Meyer. It continues the story of 18-year-old Bella Swan and her vampire love, Edward Cullen. Eclipse is the sequel to New Moon.
The story begins with a note from Jacob to Bella. It includes many sentences that he crossed out, but ends with him saying, "Yeah, I miss you too. A lot. Doesn't change anything. Sorry. -Jacob." Charlie still blames Edward for making Bella go into a zombie-like state after he left, and for being responsible for her unexplained disappearance in New Moon when she raced to Volterra, Italy to save Edward's life. He wants nothing to do with Edward, attempting to show with every word and gesture that the vampire is unwelcome in the house. Seattle is revealed to be plagued by a string of unsolved murders, which Edward suspects to be the cause of a newborn vampire that is unable to control his thirst. Charlie "un-grounds" Bella, but on the condition that she spend more time with her friends, especially Jacob, and not just Edward and Alice Cullen. Edward and Bella continue filling out their college applications, while Bella explains to Edward her desire to see Jacob again. Edward refuses, explaining that young werewolves are "unstable" and that those who associate with them often get hurt, due to the werewolves' constant angry outbursts.
Meanwhile, Alice has a vision that Victoria, the vampire that is hunting Bella, is back in town. Edward, keeping this knowledge from Bella, talks Charlie into letting them take a weekend trip to Jacksonville, Florida to see Bella's mother. When they return, Jacob confronts Edward as to why he is keeping Victoria's return a secret from Bella, also discussing the treaty's bounds, as the Cullens crossed the territorial line while chasing Victoria into werewolf territory. Edward explains to Bella that he took her away from Forks to keep her safe. Jacob and Bella reconcile, much to Edward's disapproval.
Edward insists that the only reason he doesn't want Bella seeing Jacob is because werewolves can be dangerous. Bella insists that Jacob and the rest of the pack are safe and that Jacob would never harm her. Edward finally agrees and willingly takes her, on occasion, to the border line (the area where the pact between the Quileutes and the Cullens was made, and where both can travel freely), where Jacob picks her up and takes her to his house. During one of these visits, Jacob clarifies his emotions toward Bella; he reveals that he loves her and forcefully kisses her, much to her displeasure. She reacts by punching him as hard as she can, succeeding only in breaking her hand (as werewolves are as durable as vampires).
Edward angrily threatens Jacob when Bella is brought back home. He tells him if he ever brings her back injured, he will be running on 3 legs, referring to his wolf form. He also says that if he ever kisses Bella, he will break his jaw, unless Bella asks him to kiss her. Jacob clarifies what occurred, and they grudgingly agree to work together and deal with Victoria. Later that night after Jacob leaves, Bella agrees to marry Edward on one condition: that he sleep with her before turning her into a vampire. Edward initially refuses, explaining to Bella that he could very well kill her. He eventually says, upon realizing how much it means to Bella, that he is willing to try in the future as long as they are married first. Bella expresses the worry of what other people will think if she gets married so early, as she remembers the problems that marrying fresh out of high school caused her mother. However, she realizes that spending the rest of eternity with Edward is more important to her than anything else, and when Edward formally proposes to her minutes later, she accepts. She is still reluctant to the marriage and engagement as a whole; in an attempt to keep the engagement secret, she stubbornly refuses to wear the engagement ring in public, which belonged to Edward's mother.
Bella discovers that a vampire has taken things from her room for the purpose of using her scent to locate her. Meanwhile, the Cullens realize that there is an "army" of newborn vampires committing the murders in Seattle. Bella soon makes the connection between both incidents, and realizes that the new vampires are being led by Victoria. Alice foresees a battle between Victoria's coven and the joined forces of the werewolves and the Cullens.
In order to understand the newborns' methods more clearly, Jasper tells his story. He describes, in detail, how he became a vampire and a part of the Cullen family. To the Cullens' advantage, he is an expert in dealing with newborn vampires, since he was once the "General" of a large and powerful army of newborns. The Cullens and the Quileutes arrange a meeting in the woods, and Jasper demonstrates to everyone how to fight in "newborn combat", explaining the weaknesses of newborn vampires. Bella later asks Edward to stay out of the fight because she cannot bear to lose him.
As everyone else prepares for battle, Edward and Bella camp up in the mountains, where they are later joined by Jacob and Seth Clearwater -a younger, new member of the pack- to wait out the battle. They use Bella's scent to set a trap for the newborns to follow, which will lead them to face the Cullens and the werewolves. Bella succumbs to the numbing cold at the top of the mountain, and Jacob, with the intention of taunting Edward, slips into Bella's sleeping bag in order to keep her warm (a werewolf's normal core body temperature is about 109 degrees). Hovering between sleep and conciousness, she hears a conversation between Edward and Jacob, in which Jacob openly confesses his feelings for Bella to Edward. And Edward admits that Jacob can give Bella some things that he, Edward, can't. The two of them come to an uncomfortable half-truce.
In the morning, Edward and Bella begin talking about their engagement; they hear a howl of agony, and Bella realizes that it is Jacob, who had been listening in to their conversation. He runs away before Bella can reach him, and so she asks Edward to go after him. When they come back, Edward gives them some space to talk. Jacob threatens to join the fight and get himself killed because Bella doesn't love him; when Bella begs him not to, he insists that he won't do it if she asks him to kiss her (later on, he reveals that he had tricked her into believing he would kill himself, just so he could kiss her). Furious, she does so, and she realizes that she is in love with Jacob too, although she knows she cannot live without Edward.
When Edward returns, he admits that he overheard everything and that he's not angry at her for loving and kissing Jacob; this makes Bella feel guilty, as she can see he's obviously in emotional pain. As the two stay at the camp with Seth, Victoria's newborns attack. The werewolves and Cullens make short work of her inexperienced army, but Victoria goes around the battle completely: she soon arrives to confront Bella and Edward, along with one of her newborns named Riley, who she has tricked into believing that she thinks of him as a mate. Edward tries to talk Riley out of fighting for Victoria, and tells Riley that Victoria is only using him; however, at the last second, Victoria bolsters Riley's faith in her, and he refuses to back down. A fight breaks out, and in the end Seth (in his wolf form) kills Riley as Edward destroys Victoria.
The Cullens, as well as the pack, are unharmed during the fight; but Jacob was injured when Leah Clearwater (one of the werewolves) tried to take on one of the newborns alone. Jacob stopped the vampire from killing her, but the entire right side of his body was crushed in the process. Carlisle assures Bella that Jacob is healing and that no permanent damage was done. The Volturi arrive to clean up the war, but they are too late. They remind Edward of the agreement they had to change Bella into a vampire, to which Alice replies that the date has been set.
Bella goes to visit Jacob, who is on the mend, a little while later. They both admit that they love each other, but Bella explains that her love for Edward is much greater and she can't live without him. Jacob tells her that if she ever changes her mind, he will always be there for her.
When she returns from La Push, Edward announces that he's decided to break off the deal, after seeing that Bella is trying to make everyone happy but herself. He says they needn't get married before trying to make love, as she wished. However, Bella states that she wants to do things the way he wanted to, and agrees to marry him first, then make love, then be turned. Edward places the ring back on her finger, and Bella grimly suggests that it is time to break the news to her father.
The epilogue is from Jacob's perspective. He receives an invitation to Bella and Edward's wedding, and a letter from Edward. Edward tells Jacob that he doesn't have to come to the wedding, but if their places had been switched he would have wanted the choice. He also thanks Jacob for all he's done for Bella. The letter only angers Jacob further, because he believes she is killing herself by choosing to become a vampire. Ignoring the questions, sympathy, and pleas from the rest of his pack, he changes into his wolf form and runs off, attempting to "leave Jacob Black behind." He hopes that if he doesn't phase back, he won't ever have to feel that pain again. He decides that he is no longer hurt that Bella would choose Edward over him, but he wonders how things will be between them once Bella becomes a vampire.
