Twilight book 3: Eclipse

The third book in Stephenie Meyer's vamp series, the Twilight introduced us to Bella Swan and the mysterious Cullen's a family of vampires. New Moon pulled Bella and Edward Cullen apart, and tested their love and introduced us to Jacob and the battle between wolves and vampires. It also left us hanging with a decision about Bella and immortality: when?

Eclipse is different. We return to the town of Forks and find that nothing much has changed. Graduation is closer than ever (after which, the Cullen's have agreed to make Bella a vampire) and a serial killer is loose in Seattle. Bella cannot see Jacob, her best friend because he is a Werewolf, and due to her ties to the vampires, it would break treaties and bonds made between them.

As the days go by, and graduation gets closer and closer, Bella must choose her fate. She wants to become immortal and be with Edward, but she must give up her family to do so. She is also worried about the change: will she be able to be "vegetarian" like the Cullen Family, and refrain from human blood? Or will her new blood lust cause her to kill innocent people?

The serial killer that is in Seattle turns out to be supernatural: newborn vampires on the loose. This brings up even more issues for Bella and her decision to become immortal. Not that anything could ever persuade her to give Edward up, but it makes the choice more difficult by showing her the realities of becoming a vampire.
