In a world where animals no longer exist, twelve-year-old Kester Jaynes sometimes feels like he hardly exists either.

Locked away in a home for troubled children, he's told there's something wrong with him.

So when he meets a flock of talking pigeons and a bossy cockroach, Kester thinks he's finally gone a bit mad.

But the animals have something to say...The pigeons fly Kester to a wild place where the last creatures in the land have survived.

A wise stag needs Kester's help, and together they must embark on a great journey, joined along the way by an over-enthusiastic wolf-cub, a spoilt show-cat, a dancing harvest mouse and a stubborn girl named Polly.

The animals saved Kester Jaynes. But can Kester save the animals?
