The second exhilarating novel in bestselling novelist James Patterson`s first teen series. It`s 24 hours since Max Ride and her fellow bird-kids escaped the New York Institute, and they`re still on the run. But the six companions - 98% human, 2% bird - came away with some vital information. If they can decode the garbled words and numbers, perhaps they`ll find out where their parents are. There`s a lot of trouble ahead for Max, Fang, Iggy, Nudge, the Gasman and Angel - not to mention Total, the talking dog. Their enemies, the fearsome Erasers, have acquired a new skill - they too can now fly. After an air-battle, Fang ends up in hospital. The FBI track down the flock, who`ve become more visible than they ever wanted to be. They even end up going to school! But that doesn`t quite fit in with searching for parents, or with what the insistent Voice in Max`s head keeps reminding her - that her mission is `to save the world`.
