"Sixteen-year-old Alex is a Spinner--she has the ability to rewind time to review past events. Hated and feared because of their ability to find the truth, the small population of Spinners is restricted to Centers--compounds created to house and protect them. Alex's society uses the Spinners' skills to solve major crimes, but messing with time comes with consequences: no Spinner lives past the age of twenty. At sixteen, Alex is in her prime--until time sickness strikes early. When she is offered an experimental treatment, Alex sees a future for herself for the first time. But the promising medication offers more than just a cure--it also brings with it dire consequences."--Amazon.com.

In a world where spinners can freeze and rewind time but are tightly controlled by the government, sixteen-year-old Alex is a spinner paired with Agent Ross to help catch a dangerous criminal.
