The third book Eclipse starts with reports of disappearances and violent murders in Seattle. This is discovered to be the work of Victoria, mate of the tracker from the first book who died, creating an army to ultimately kill Bella.Victoria blames Bella for the death of her partner. Bella and Edward also start to decide what Bella will do after school is over.

Bella tries to have sex with Edward but the refuses citing that he could kill her if they tried. This leads to Edward proposing to Bella and promising to have sex once they're married. ( the post martial sex idea maybe due to the author being a Mormon). Bella excepts half heartedly because she thinks marriage for teenagers is old fashioned and doesn't like to thought of being like her mother, who got married early.

The Cullen and Jacobs gang ( who the readers found out can morph into werewolves) devise the a plan to destroy Victoria's advancing army. They destroy the advancing army but Edward is hurt and is saved by Carlise ( Edward's father) .
