When Laura's sister disappears in Milan, the most dangerous part of the search may be falling for the man who wants to help her...

A weekend in Milan with her student sister, Charlie, should be a welcome break in Laura's stressful life. When Charlie fails to meet her at the airport as arranged, Laura isn't too concerned at first. After all, her sister has always been impulsive and forgetful where she is cautious and thoughtful. But when she goes to Charlie's apartment, only for the landlady to tell her she hasn't seen Charlie for several days, Laura begins to worry something sinister has happened.

With the aid of Gianmario de Rossi, Charlie's personal tutor, begins to probe the mystery of Charlie's disappearance. But how much does the handsome, intelligent Gianmario know about what's really happened to Charlie, and by giving in to her impulse to have wild, passionate sex with him, is Laura being lured to a similar fate?
