Our city. Our secret. Our rules.

When pupils start going missing from a prestigious boarding school, Ollie Turner knows it’s a job for the Haven.

Below the city streets, the Haven is a sanctuary for kids run by kids.

Ollie and the Haven’s investigations team put their lives on the line, going undercover to find the missing children. But little do they realise that a deadly enemy awaits them - one with plans to destroy everything they hold dear.
