Why is everyone trying to kill Prissi Langue?It's 2097 and teens can fledge and grow wings as they go through puberty. Fifteen year old Prissi has been having fun flying, goofing with her BFF Nancy, and stirring up arguments with her NQB (not quite boyfriend) Joe Fflowers. Despite her mother's death three years before, her dad's unending and very depressing grief, and Joe's threats to run away from school to avoid fledging, Prissi's life is pretty good.That is, until Prissi meets Joshua Fflowers, the man who invented fledging and one of the world's richest men. Intrigued with Joshua Fflowers, Prissi does some research and finds a picture of him with someone who looks just like her mother—except that her name is different and her dad professes to know nothing about it.As Prissi investigates, she meets a man who worked with her mother on some radical meta-mutational research a half-century before. Intrigued, Prissi keeps investigating and before she knows it her good life is gone.The chase is on. Over the skies of Manhattan, into the bowels of the drowned subway system, across the wasteland of eastern Long Island, the question becomes can Prissi fly fast enough and far enough to elude all the people who are trying to kill her?
