Maximum Ride: The Angel Experiment

WELCOME TO MY NIGHTMARE Do not put this book down. I'm dead serious - your life could depend on it. I'm risking everything by telling you - but you need to know.
STRAP YOURSELF IN for the thrill ride you'll want to take again and again! From Death Valley, California, to the bowels of the New York City subway system, you're about to take off on a heart-stopping adventure that will blow you away...
YOUR FAITHFUL COMPANIONS: Max, Fang, Iggy, Nudge, the Gasman and Angel. Six kids who are pretty normal in most ways - except that they're 98% human, 2% bird. They grew up in a lab, living like rats in cages, but now they're free. Aside, of course, from the fact that they're prime prey for Erasers - wicked wolf-like creatures with a taste for flying humans.
THE MISSIONS: Rescue Angel from malicious mutants. Infiltrate a secret facility to track down the flock's missing parents. Scavenge for sustenance. Get revenge on an evil traitor. And save the world. If there's time.
