Six of Crows by Leigh 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

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.
