Six of Crows - Six of Crows #1 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.
