Six of Crows (Six of Crows, #1)

by Leigh Bardugo

The boy they called Dirtyhands didn’t need a reason any more than he needed permission – to break a leg, sever an alliance, or change a man’s fortunes with the turn of a card.

Kaz always had his reasons. Inej could just never be sure they were good ones.

Kaz shook his head, dark hair glinting in the lamplight. He was a collection of hard lines and tailored edges – sharp jaw, lean build, wool coat snug across his shoulders.
