The following is a review of this possible summer reading choice from Booklist:
Appropriate for grades 7-10. Living with an unpredictable, psychotic mother has taught Matthew how to survive. Constantly on alert, he and his sister, Callie, devotedly shelter their younger stepsister, Emmy, from their mother's abuse and worry about staying safe. Matt insists that "fear isn't actually a bad thing . . . . It warns you to pay attention, because you're in danger. It tells you to do something, to act, to save yourself," but his terror is palpable in this haunting, powerful portrayal of domestic dysfunction, which is written in retrospect as a letter from Matt to Emmy. Unfortunately, the adults in the children's life, a distant father and an apathetic aunt, don't help, though Matt sees a spark of hope in Murdoch, who dates his mother, Nikki, and then leaves when he becomes another target for her escalating rage. It is Murdoch, with a violent past of his own, who is willing to risk getting involved and eventually becomes the change agent that the children so desperately need. The author of Double Helix (2003),Werlin reinforces her reputation as a master of the YA thriller, pulling off a brilliant departure in this dark but hopeful tale, with pacing and suspense guaranteed to leave readers breathlessly turning the pages.
