MAXIMUM RIDE: THE FINAL WARNING by James Patterson

From the cover:

"Join six extraordinary kids for their coolest ride yet . . . In one of the world's most extreme environments - the freezing South Pole - Max and the flock are in serious trouble. The grotesque Uber-Director has put a price on their heads, and a worldwide auction for the genetically modified kids is about to begin. His mutant army is heading south to track down the winged gang, and with no built-in function for mercy the soldiers aren't about to take pity on anyone. Oblivious to the Uber-Director's evil plans, the flock is on a special government mission to save the Earth. But in a brutal environment like the South Pole, being able to fly isn't always an option for escaping from your worst nightmares . . . "
