Ivan Kozlov doesn't make mistakes, no matter what his brothers might say. Mistakes in his world mean death. So while he may have summoned the wrong sort of demon to aid him in cementing his empire, binding himself to the creature with an irreversible contract, that doesn't mean he can't make use of him. Except the seductive incubus he's summoned seems to want more from Ivan than just a piece of his soul. Nix wants Ivan's body, his desire, his faults and his regrets. But giving those things to him would be a mistake. And one Ivan might never recover from.

Nix has been waiting to be summoned again for ages. And while he might have had to trick his handsome mob boss to make it happen, he's not going to waste the opportunity while he has it. Only now that he's here, he doesn't just want to stay in the human realm. He wants Ivan—his greed and his rage and his lust. And if Nix has to fix Ivan's life to make that happen—if he needs to handle the dangers in his business, mend the broken bits left by Ivan's father—then that's what he'll do. Even an incubus can be useful to a mobster, if given the right incentive.
