Eclipse: Bella once again finds herself surrounded by danger as Seattle is ravaged by a string of mysterious killings and a malicious vampire continues her quest for revenge. In the midst of it all, she is forced to choose between her love for Edward and her friendship with Jacob -- knowing that her decision has the potential to ignite the struggle between vampire and werewolf. With her graduation quickly approaching, Bella is confronted with the most important decision of her life.
Bella and the Cullens soon realize that the Seattle murders are being committed by an "army" of newborn vampires, controlled by Victoria. The Cullens join forces with the wolf pack to combat this threat. As everyone else prepares for battle, Edward, Bella, and Jacob camp in the mountains, hidden during the battle, where they are later joined by Seth Clearwater, a young wolf pack member, to wait out the fight.
In the morning, Jacob becomes upset when he overhears Edward and Bella discussing their engagement and threatens to join the fight and get himself killed. To stop him, Bella kisses Jacob and comes to realize that she is in love with him as well. During the battle, Victoria tracks Edward's scent to Bella's forest hiding place, and Edward is forced to fight. Edward manages to decapitate Victoria and her vampire army is destroyed. Afterwards, Bella explains to Jacob that while she loves him, her love for Edward is greater. After receiving a wedding invitation from Edward, Jacob runs away in his wolf form to escape his heartbreak over Bella's decision to become a vampire.
