Taste of Karma by Heather Long

Death, Sin, and Vengeance walk into a bar…
They all want something from Karmen.
Bish wants to get even with Karmen for her interference in taking Dahlia away from him. Cipher wants to punish her for abandoning his arms and his bed. Váli has wanted her for centuries but she never seemed to see him.
When Bish and Cipher conspire to teach Karmen a lesson, Váli seizes the opportunity and offers his services—after all, Vengeance is his grace. Too bad for them, he’ll extract a little for his girl and eliminate them as competition at the same time. These bad boys are no angels.
Karma has no deadline…
I’m not afraid of them. I’m not afraid of anyone.
Sin betrayed me, Death wants me to pay, and Vengeance? He’s all right, but we work together too much. Our methods are very different. When those three Keepers put their heads together, my spine tingles in warning. They’re up to something and it’s hard to miss. I’ve played this game for far too long. Are they really sure they want to mess with me?
Bring it on, boys. I’m patient and it’s hardly the first time I got my hands dirty.
