In The Blood - Lisa Unger - Simon and Schuster

Lana Granger lives a life of lies. She has told so many that the truth is like a hazy nightmare she can’t quite recall. About to graduate from college and with her trust fund almost tapped out, she takes a job babysitting a troubled boy named Luke. Expelled from schools all over the country, the manipulative young Luke is accustomed to controlling the people in his life. But, in Lana, he may have met his match. Or has Lana met hers?

When Lana’s closest friend, Beck, mysteriously disappears, she resumes her lying ways—to friends, to the police, to herself. After all, she will do anything to hide the truth about her whereabouts the night Beck disappeared but it might not be enough to keep her ominous secrets buried: someone else knows about Lana’s lies. And he’s dying to tell.
