Bella must choose between her friendship with Jacob, a werewolf, and her relationship with Edward, a vampire, but when Seattle is ravaged by a mysterious string of killings, the three of them need to decide whether their personal lives are more important than the well-being of an entire city.

Having made her choice between living a fully human life or joining the world of immortals to be with her beloved Edward, Bella finds her future threatened by a series of events with potentially disastrous consequences.

When seventeen-year-old Bella leaves Phoenix to live with her father in Forks, Washington, she meets an exquisitely handsome boy at school for whom she feels an overwhelming attraction and who she comes to realize is not wholly human.

When the Cullens, including her beloved Edward, leave Forks rather than risk revealing that they are vampires, it is almost too much for eighteen-year-old Bella to bear, but she finds solace in her friend Jacob until he is drawn into a "cult" and changes in terrible ways.
