Hidden at the intersection of several busy highways behind the trees and scrubby undergrowth is an island, full of secrets. Pez has lived there for a while now, enjoying the solitude. She has a vegetable patch, a routine, her own way of doing things and a condor, who may be outstaying his welcome. Runaway brothers, Riley and Grayson call the island home too. They keep their distance from Pez and spend precarious days trying to survive, still relying on the man-made world which speeds around them. Then Gil arrives, with his hagstone and a dream of happy families, and everything changes. The four of them find a way of living and believe they might stay on the island forever. But all too soon they witness something they should never have seen and they're in deadly danger.
