P. Djèlí Clark The Dead Cat Tail Assassins

Eveen the Eviscerator is skilled, discreet, professional, and here for your most pressing needs in the ancient city of Tal Abisi. Her guild is strong, her blades are sharp, and her rules are simple. Those sworn to the Matron of Assassins - resurrected, deadly, wiped of their memories - have only three unbreakable vows. First, the contract must be just. That's above Eveen's pay grade. Second, even the most powerful assassin may only kill the contracted. Eveen's a professional. She's never missed her mark. The third and the simplest: once you accept a job, you must carry it out. And if you stray? A final death would be a mercy. When the Festival of the Clockwork King turns the city upside down, Eveen's newest mission brings her face-to-face with a past she isn't supposed to remember and a vow she can't forget.
