Jenna wakes up from a coma and discovers that she has no memory of the past year. Things are decidedly strange in her new home, her parents are desperate for her to remember the "jenna" she was, her grandmother seems to hate her, and she can't figure out why they are hidden away in a small California town instead of home in Massachusetts. In a sci-fi thriller-ish way, Jenna finds that she is not the person she used to be and that her parents are responsible for criminal actions.
As I read this, I was heavily reminded of Eva by Peter Dickinson. I think Jenna will have great teen appeal, but I didn't find the writing to be all that remarkable. It gets a maybe from me. I'm anxious to hear what others think.
