Ketterdam is a city built on trade and crime, where the Merchant Council looks the other way and the gangs run everything below the surface. Kaz Brekker, the most feared teenager in the city's most powerful gang, is offered a job that should be impossible: break into the most secure prison in the world and extract a hostage worth more than any of them can imagine. He assembles a crew of specialists: a convict, a sharpshooter, a runaway, a spy, a Grisha. A duology that runs parallel to the events of Shadow and Bone, set in a different country with a different tone: darker, funnier, and more interested in what loyalty costs when everyone involved has reasons to betray everyone else.
