When Jesper goes to meet with his father, they are attacked but manage to escape. Meanwhile, Jesper’s father, Colm, arrives at the city to meet him, as the bank is pushing the deadline for the debt Jesper owes. After they find what they need, Kaz plans to kidnap Van Eck’s pregnant young wife, Alys, and trade her for Inej, who is being held captive and is nearly tortured. The book commences in a gambling parlor known as Club Cumulus where Jesper and Nina keep Jan Van Eck's lawyer, Cornelis Smeet, busy while Kaz and Wylan search his office for Jan Van Eck's property information. In the prologue, a Grisha man named Emil Retvenko is kidnapped by a winged Shu man. A war will be waged on the city's dark and twisting streets―a battle for revenge and redemption that will decide the fate of magic in the Grisha world.


As powerful forces from around the world descend on Ketterdam to root out the secrets of the dangerous drug known as jurda parem, old rivals and new enemies emerge to challenge Kaz's cunning and test the team's fragile loyalties. Double-crossed and left crippled by the kidnapping of a valuable team member, the crew is low on resources, allies, and hope. But instead of divvying up a fat reward, they're right back to fighting for their lives.

Kaz Brekker and his crew have just pulled off a heist so daring, even they didn't think they'd survive. "To Holly and Sara, who helped me build Noa, who made sure the walls stayed standing Jo, who kept me standing too."
