But some of them can see him in return. And he looks juicy. How can a small boy protect himself from magical predators he barely understands? By becoming the disciple of a man who walks in both worlds. While other kids are at cricket practice, Tom is learning to deal with demons, trading pieces of himself for safety and power. But how much will be left by the time he's ready to graduate? And what will he do if his mum finds out? Discipline is a gripping fantasy tale, taking you from a small country town in Australia to the gates of Hell.
