My Sentient Parasite is Infatuated with a Vampire!

Quinn has worked for a decade as the spa manager at Firebaugh Resort. The luxury home away from home for the magically inclined. Besides managing the spa, he takes private clients as a wellness coach, often using an ability which allows him to calm those around him. What no one knows is that his ability isn't because he's fae, but the result of playing host to a parasitic worm.

Helmin, the parasite, helps create a calming pheromone that benefits Quinn in his work. It often has opinions about how much Quinn allows it to feed on negative energies that help create the pheromones, and it especially has thoughts that only Quinn hears about their vampire client, Mateo.

Mateo, a long-time client of Quinn's and a trauma survivor, arrives at the resort one night in a distraught state, requesting Quinn's help. Quinn tries to assist only to end up in a complicated situation between Helmin and Mateo. Where Helmin controls Quinn's bodily responses, and Mateo has no idea Quinn is caught in the middle.

Once Quinn reveals Helmin to Mateo, the three embark on an exploration of the mind and body unlike any they've experienced before.
