After a tumultuous beginning, mid-23rd-century Earth now peacefully operates under the constant surveillance of the Watcher, an all-seeing AI who has seized control of the planet�and of the minds and bodies of its people. But is the radical evolution that the Watcher has in mind a step forward or the beginning of a mighty split that will cast aside everything that truly makes us human?It is 2252, and Judy is traveling on a passenger ship in deep space when disaster strikes. Almost too conveniently, strange machines appear onboard just in time to help. They are owned by DIANA, a commercial organization headquartered on Earth. But as the machines arrange for the humans to be taken to safety, Judy is held back. They have detected something in her genetic code�something shocking: Judy is not human. And she too is the property of DIANA.Now Judy must return to Earth to find out what DIANA expects of her�how she was grown�and why she was destined to destroy the Watcher. But is this Judy even the same person? And does the new Judy have a reason to destroy�or is she just a pawn in someone else�s murderous game?
