Maximum Ride 4

The Flock members are taken under the wing of an FBI agent and try to live "normal" lives by going to school, making friends--and continuing their relentless search for their parents. But the Erasers return, forcing the Flock to abandon their search and make their escape once again. It's also becoming more obvious to Max that her destiny is to save the world, and this is especially challenging to do when she is faced with her ultimate match: a newer and better version of herself, Maximum Ride II.
