Five events that lead to the climax:
- Bella Swan moves to Forks, Washington
- Bella encounters Edward Cullen in science class and is rescued by him from being crushed by an out of control van
- Bella falls in love with Edward
- Bella discovers that the Cullenses are vampires
- Bella plays baseball with the Cullenses and encounters James, Laurent, and Victoria
I would say that the climax is James's attack of Bella and fight with Edward.
