'Once again Possum and Mopoke venture beyond the safety of The Valley with the Collector Desert Wind. This time they search for more than metal or new plants; they have a mystery to solve even stranger than the music from the sea or the city in the sand. Where did the wild boy Dommy come from? And how could he have tamed lions? It is a time not so far in the future and our world has changed completely. This series tells of the 'Children of the Valley', of their learning to live with nature, of their expeditions from the sheltered ridges into the hot wild world beyond, and of the wonders they find there.'
