For Tristan Todorov, formerly a freelance magician and now a consultant on occult matters, living with an incubus turns out to be rather challenging. Not only because there's little information on incubi, Gomorrah pleasure demons. Jarek, the one he has a contract with, has a fiery personality and a dark past, and sometimes he's a mystery Tristan can't decipher.

When Tristan ends up in possession of an illegal artifact with peculiar powers, he hopes it might help him and Jarek to finally understand each other. Will it be a blessing indeed—or a curse that might put them both in danger?
