It's 24 hours since Max Ride and her fellow bird-kids escaped the New York Institute‚ and they're still on the run. The six companions - 98% human‚ 2% bird - come away with vital information. If they can decode the garbled words and numbers‚ perhaps they'll find out where their... More 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‚ the badly hurt Fang ends up in hospital. The FBI track down the flock; 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'.
