Six of Crows (Six of Crows, Book 1)

Ketterdam: a bustling hub of international trade where anything can be had for the right price―and no one knows that better than criminal prodigy Kaz Brekker. Kaz is offered a chance at a deadly heist that could make him rich beyond his wildest dreams. But he can't pull it off alone. A convict with a thirst for revenge. A sharpshooter who can't walk away from a wager. A runaway with a privileged past. A spy known as the Wraith. A Heartrender using her magic to survive the slums. A thief with a gift for unlikely escapes. Six dangerous outcasts. One impossible heist. Kaz's crew is the only thing that might stand between the world and destruction―if they don't kill each other first.
