Mateo Borrero has ninety-nine problems, and all of them hinge on the fact that his terrifying and currently-missing bruja mother trapped a demon in his body when he was born. His mother forbade him from ever using magic, but now that she’s gone, magic’s his only marketable skill, and he’d really like an exorcism—which costs money he doesn’t have. What’s the harm in making a quick buck by calling himself an Occult Specialist and chanting a few half-remembered spells in his crappy Spanish?

Enter Topher, a naive nepo baby with a curse that keeps killing people around him. Most importantly, he’s rich, and too clueless to clock that Mateo–and his (absolutely-not-the-assistant) astral-projecting best friend Ophelia–have never actually had a client before. Lifting Topher’s bad luck curse should be simple, but as luck would have it, nothing is simple, and Topher–who Mateo sort of, kind of likes–might be at the center of a deadly magical conspiracy. 

To make matters worse, the more magic Mateo does, the stronger the demon inside him grows and the more he wants to eat people. But would caving to the urges of an ancient evil really be that bad if it helps him get a payday?
