Rewind by Carolyn O'Doherty

Alex is a spinner meaning she can rewind time to view past events (but no more than a day or so). The world fears spinners so she and the others are locked up together in a facility. On those rare occasions when they are allowed to go out, they must wear a band that keeps them from rewinding time.

Upside to being a spinner: they assist the police in solving and preventing crimes. Alex is one of the better ones, so she gets to help with murders and bomb attempts.

Downside: spinners eventually get the disease and die before they are 20 years old. And they have a implanted chip that tracks them.

Alex is happy with her assigned police officer, Agent Ross. He is not afraid of her abilities and sees their potential in helping him track a criminal he has wanted to catch for a long time. Ross even bends some rules so Alex can help.

But it's a dangerous world when you are pursuing powerful criminals in a world where most people do not like your powers already. Even the facility is not safe when Alex can't trust the staff to do what is in her and the others' best interests. KJ, her best friend, is the only person she truly trusts, but things have been strained between them since he has shown interest in another girl.

Can Alex avoid the disease and help catch a killer? Or will Alex have to escape from her confined world? And who will help her?
