Rowan Sterling should be worrying about normal teenage things like attending college and whether her best friend Lucas is maybe more than a friend...Instead, she’s having terrifying visions of blood and violence. Rowan then finds herself drugged, kidnapped, and sent to Rosewood: a training center for teens with special abilities who are known as Harrows, who can view the actions of would-be murderers before they commit crimes. When they are apprehended by a Harrow, imminent criminals, known as imcrims, are captured and indefinitely detained in a state of sedation. However, how can it be ethical to imprison people who haven’t actually done anything yet? Rowan returns home, but when she reunites with Lucas, she has a vision of him shooting a man in cold blood. Now Rowan is questioning everything she learned at Rosewood, and sets out to protect him from the Harrows.
