Whitley Johnson's dream summer with her divorced father turns into a nightmare. She had just met his new bride and her children. The bride's son is Whitley's one-night stand from prom. Just damn great! What's worse is that Whitley doesn't fit into his father's new ideal family at all. Therefore, Whitley behaves provocatively. She goes to parties. Having fun until you drop. He's having so much fun that he doesn't even notice the good things: his cute future stepsister, she's the only one Whitley likes; best friend and handsome guy who is not her stepbrother... at least not yet. All three of them will help Whitley deal with her anger and begin to put the pieces of her family back together.
