Sarah O'Brien is only alive because of the pact she and her brother made twelve years ago-James will protect her from their violent father if she promises never to leave him. For years, she's watched James destroy his life to save hers. If all he asks for in return is her affection, she'll give it freely.



Until he asks for more than she can give.



Sam Donavon has been James's best friend-and the boy Sarah's had a crush on-for as long as she can remember. As their forbidden relationship deepens, Sarah knows she's in trouble. Quiet, serious Sam has decided he's going to save her. Neither of them realizes James is far more unstable than her father ever was.



And James is not about to let Sarah forget her half of the pact . . .
