Close Quarter by Anna Zabo

On a transatlantic cruise to New York, sculptor Rhys Matherton struggles to piece his life back together after losing his mother, inheriting a fortune, and finding out his father isn’t his father after all. He spills a tray of drinks on a handsome stranger, then he finds himself up against a wall getting the best hand-job he’s ever had. And for the first time in his life, he feels whole.

Rhys enjoys the company of Silas Quint, but for the eerie way no one pays attention to them even while they kiss in a crowded bar. Silas explains he’s a forest fae able to glamor the room around them—and more importantly, that he’s on the cruise to hunt vampires. Rhys thinks Silas is full of it, until he discovers vampires are real, and he’s part of their main course.

Silas Quint can’t be distracted by a human lover, even one as lovely as Rhys. Stuck in the middle of the ocean, he has barely enough of energy to hunt the vampires he’s been sent to destroy. Rhys is full of the one thing Silas needs needs most—the element of living plants. Only sucking energy from Rhys would make Silas as soulless as the creatures he hunts. How can he keep Rhys safe, without becoming like the very monsters he hunts?
