Is evil born or bred? This is the question Bennie Rosato must answer after her twin sister, Alice Connolly, drugs her and leaves for dead, buried underground in a remote field. As Alice slips easily into Bennie’s life, doing her job, interacting with her friends, seducing her boyfriend, she never counts on the fact that Bennie is tougher than she seems. And that, against all odds, Bennie will escape. But escaping is only the first challenge. Alice’s sociopathic lies are so believable that she has everyone convinced that she is Bennie, and Bennie is her deranged twin sister Alice. As Bennie descends further into Alice’s life, she starts to feel the pull of evil herself. As the clock ticks and Alice gets closer to her ultimate goal, Bennie must face the shocking truth that she is perhaps more like Alice than she ever realized.
