Whitley Johnson's dream summer with her divorcé dad has turned into a nightmare. She's just met his new fiancée and her kids. The fiancée's son? Whitley's one-night stand from graduation night. Just freakin' great. Worse, she totally doesn't fit in with her dad's perfect new country-club family. So Whitley acts out. She parties. Hard. So hard she doesn't even notice the good things right under her nose: a sweet little future stepsister who is just about the only person she's ever liked, a best friend (even though Whitley swears she doesn't "do" friends), and a smoking-hot guy who isn't her stepbrother...at least, not yet. It will take all three of them to help Whitley get through her anger and begin to put the pieces of her family together.
