In Rosewood, Pennsylvania, four perfect-looking girls aren't nearly as perfect as they seem.

Aria can't resist her forbidden ex. Hanna is on the verge of losing her BFF. Emily is freaking out over a simple kiss. And Spencer can't keep her hands off "anything" that belongs to her sister.

"Lucky me." I know these pretty little liars better than they know themselves. But it's hard keeping all of their secrets to myself. They better do as I say . . . or "else"!
