"Bennie Rosato looks exactly like her identical twin, Alice Connelly, but the darkness in Alice's soul makes them two very different women. Or at least that's what Bennie believes--until she finds herself buried alive at the hands of her twin. Meanwhile, Alice takes over Bennie's life, impersonating her at work and even seducing her boyfriend in order to escape the deadly mess she has made of her own life. But Alice underestimates Bennie and the evil she has unleashed in her twin's psyche. Soon Bennie, in her determination to stay alive long enough to exact revenge, must face the twisted truth that she is more like Alice than she could have ever imagined...and by the novel's shocking conclusion, Bennie finds herself engaged in a war she cannot win--with herself."-- From back cover.
