And then Fella, an orphan, discovers a diary, hidden fifteen years ago by his mother - a woman who seemingly came from the Outside, from a world not run by the Officiate.

This revelation seems incredible, but it gives the two friends hope that they can escape the brutality of their lives.

Yet when, after a gripping chase, they manage to get off the island, what they discover is a shock.
