Six of Crows by Leigh Bardugo
Welcome to the world of the Grisha, where magical powers are real, everyday occurrences, even if some people don't think they should be! Inej is part of the Dreggs, which is a gang that runs part of Ketterdam, but not all of it, since a bunch of other groups are vying for it as well. Still when Kaz - the second in command of the Dreggs, for lack of a better term, gets the opportunity to pull off the heist of a lifetime, with just as great a reward, he can't say no. And neither can some of his most trusted members. But it is a job that could very well get them all killed.
