Eclipse - Stephenie Meyer (Twilight #3)

Bella?

Edward's soft voice came from behind me. He pulled me into his arms at once, and kissed me. His kiss frightened me. There was too much tension, too strong an edge to the way his lips crushed mine — like he was afraid we had only so much time left to us.

As Seattle is ravaged by a string of mysterious killings and a malicious vampire continues her quest for revenge, Bella once again finds herself surrounded by danger. 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 ageless struggle between vampire and werewolf. With her graduation approaching, Bella has one more decision to make: life or death. But which is which?
