Six of Crows by Bardugo
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.
Kaz's crew is the only thing that might stand between the world and destruction—if they don't kill each other first.
