White Rabbit by Caleb Roehrig

Rufus Holt is having the worst night of his life. It begins with the reappearance of his ex-boyfriend, Sebastian—the guy who stomped his heart out like a spent cigarette. Just as Rufus is getting ready to move on, Sebastian turns up out of the blue, saying they need to “talk.” Things couldn’t get much worse, right?

But then Rufus gets a call from his sister April, begging for help. And then he and Sebastian find her, drenched in blood and holding a knife, beside the dead body of her boyfriend, Fox Whitney.

April swears she didn’t kill Fox—but Rufus knows her too well to believe she’s telling him the whole truth. April has something he needs, though, and her price is his help. Now, with no one to trust but the boy he wants to hate yet can’t stop loving, Rufus has one night to prove his sister’s innocence…or die trying.
