It's Gabriel's fourth year at Crookhaven School for Thieves, and it's the most challenging one yet. Along with mastering a new class - Lay of the Land - Upper Delinquents are expected to start thinking about life after Crookhaven. Their schoolwork is beginning to have real-world implications, and this year's Break-In challenge takes place in an external location known to be impenetrable - the Impossible Fortress.

But the world outside their school grounds can be a dark and dangerous place. And with the most powerful crew in the underworld, infamously known as the Nameless, out to get Gabriel and his friends, the stakes have never been higher. The crew needs to put everything they've learned so far to the test outside of Crookhaven's gates.

And there might be something lurking within those gates that the crew should be cautious of too... The fourth book in the 'criminally good' Crookhaven series, the secret school where students are taught to do wrong, so that one day, they can set the world right.
