Eclipse (The Twilight Saga, Book 3) - Stephenie Meyer My least favorite book in the series (sorry).
Why?
Because of that hormones driven, pushy teenage boy running desperately around like wolf puppy.
And I couldn't get over Jacob's controversial argument on Bella should pick him instead of Edward 'cause he's warm with a heart beat and he doesn't mean continuous threat to Bella.
Okay, so does it ever occur to him (or anybody else) that he's a werewolf, and if he gets angry and you're nearby no top plastic surgeon can fix you (assuming you survive).

Peek moments: Edward's bed, hostage situation, "marry me", Seth, Rose's story, Volturi guard, Third Wife, battle training session.
