Unleashed (First edition)

 
Alex has the ability to freeze time and to rewind it. She and three other time spinners have successfully escaped the government facility that had imprisoned them. At last, they are free.  Or are they?
 
How free can you be in a world that fears spinners-imprisoning them, medicating them, and killing them before they reach adulthood? How free can you be when you know that the twenty other spinners you grew up with are still trapped? How free can you be when the police officer you used to work for is determined to track you down?
 
In this second book in the riveting Rewind trilogy, Alex finds that the city outside the Center is more complicated and dangerous than she'd imagined-and that some of the dangers lie within herself.
