Maximum Ride, Vol. 5 by NaRae Lee

Escaping ITEX in Florida, the Flock head west, with Max more burdened than ever by the knowledge that she's meant to save the world. But while their leader is keen to stay on the path leading to her destiny, Fang and the others are more interested in settling down and letting the chips fall where they may. With the Erasers eerily absent from their lives of late, has the Flock finally earned a bit of peace...or is this all just the calm before the storm?
