The Angel Experiment: A Maximum Ride Novel (Book 1) / James Patterson,

Maximum Ride and her "flock" -- Fang, Iggy, Nudge, Gasman and Angel -- are just like ordinary kids, only they have wings and can fly. It may seem like a dream come true to some, but their lives can morph into a living nightmare at any time.

Angel, the youngest member of the flock, is kidnapped and taken back to the "School" where she and the others were experimented on by a crew of whack jobs. Her friends brave a journey to blazing hot Death Valley, CA, to save Angel, but soon enough, they find themselves in yet another nightmare: fighting off the half-human, half-wolf "Erasers" in New York City. Whether in the treetops of Central Park or in the bowels of the Manhattan subway system, Max and her adopted family take the ride of their lives.

Along the way, Max discovers that her purpose is save the world. But can she?
