Ever since the floods came and washed the world away, survivors have been desperate to win a place on X-Isle, the island where life is rumoured to be easier than on what's left of the mainland. Only young boys are in with a chance, the smaller and lighter the better.

Baz and Ray are two of the lucky few to be chosen, but they soon discover that X-Isle is a far cry from paradise. Ruled by Preacher John, a dangerous religious fanatic, it's a violent, unpredictable place where terrible things can happen at any moment.

The boys hatch an extraordinary plan in order to protect themselves—the construction of a mighty weapon of defence. But can they complete this weapon in time, and are they really prepared to use it in order to secure their freedom?

Powerful and compelling, X-Isle is a fast-moving thriller that will keep you guessing right to the very end.
