What should a 16-year-old girl with no memories trust: her own instincts or the cryptic words of a boy who insists she knows him?
Our heroine washes ashore when the book opens, apparently the sole survivor of a plane crash. Dubbed Violet by a nurse after her (yes, violet) eye color, she becomes a national news story and is quietly sent to a foster family in northern California when no one steps forward to identify her. The only person she meets who claims to know her is a boy who appears mysteriously when she's alone and warns her that she's in danger. Short, dramatic, present-tense sentences move the action forward, and the book's central questions (who is Violet? who is following her? when will she start believing the boy who is clearly the romantic lead?) provide plenty of suspense. Although the mysterious boy is more of an archetype than a character in his own right, Violet's 13-year-old foster brother Cody is pleasingly funny, suspicious and competent. There are intriguing sci-fi elements at play, but analytical readers will notice holes in the workings of genetics and the logistics of time travel.
Fast-paced and sure to satisfy romance-oriented readers, if not skeptics. (Science fiction. 12-18)
