In this tense and pacey novel exploding with intrigue and action, a lone survivor of an explosion on a plane wakes up without her memory and must determine who she is and where she came from. But this soon proves difficult, with the only clue to her identity coming from a mysterious boy who claims she was part of a top-secret science experiment, and the only adult she trusts telling her that she shouldn't believe anything that anyone tells her... The sequel, "Unforgotten", also comes out this month.
