Jessica and Elizabeth Wakefield have no idea that their world is about to be turned upside down - again. Last Christmas, Margo - a girl who looked, talked and dressed exactly like Jessica and Elizabeth - arrived in Sweet Valley to take what she considered her rightful place in the Wakefield home. On a dark winter's night, Margo fell to a violent death, and the Wakefields thought their nightmare was over.
But they didn't know about Nora, Margo's own twin sister. Nora, separated from Margo at birth, is outraged when she discovers that the sister she'd never known is dead . . . and that California's picture-perfect twins are to blame. Now Nora wants revenge - and she's capable of evil beyond anything Margo could have ever dreamed.
