When Livy's accepted at Temple College, a school for the very brightest, no one is more surprised than her, though she has always felt different. Recently, Livy's been drawn to the roof, where, among its towering stone angels, she has the strangest desire to fly. But her behaviour is noticed by others, for whom the ability to defy gravity is a possible reality ... one that they'll stop at nothing to use for their own ends.
