Captured by a mysterious army just as they escaped a Campton overrun with `zombie' children, Dodzi's group, along with what's left of the Clan of the Shark, discover an entire civilisation, ruled over by children who have been in the In-Between-World for a long, long time. Strict rules, a caste system, bizarre superstitions... All new obstacles for the group to overcome - although Saul is being treated like a messiah. And over it all hangs the threat of the sinister Midnight Child...
