The second exhilarating novel in 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!
