Twelve-year-old Kester thought he had discovered the last wild animals in the land. He thought his adventure was over. He was wrong.

Below the sparkling city of Premium, deep underground, a dark wild remains: animals who believe the time is right to rise up against their human enemies.

And soon Kester realises: he is the only one who can stop them.

Kester Jaynes saved the animals. Can he save the humans too?
