Sixteen-year-old Alex Manning has a rare gift: she’s a spinner who can freeze and even rewind time. Hated and feared, spinners are housed in Centers, where they are carefully monitored and medicated. They are let outside for only one purpose: to use their gift to help solve crimes. Each spinner is paired with an officer, and Alex hit the jackpot—an agent who actually values her skills. She and Agent Ross are secretly trying to catch a dangerous criminal, a task that will take time. But time is something Alex doesn’t have. No spinner lives past twenty. When Agent Ross reveals that he knows about an experimental treatment to help her, Alex suddenly sees a future for herself that she never imagined—time to solve the case and maybe even a chance to tell her best friend how she really feels about him. But the promising medication brings with it an ability that would terrify the world an even put other spinners in danger. Are the benefits worth the risk?
