Unsalvageable - Sanguine Blood Seekers, #1

Vampires are real! Sten Majkovic has lived longer than he ever dreamed possible. Among his kind it isn't easy having a slim, lithe build, but it does have advantages in the human world. He welcomes attention of men who appreciate his appearance. Their mistake is expecting to hold the upper hand. None ever do. And not a single one of them realizes his rabid need for blood -- until it's too late. Drew Riles' life is shitty.
Mid-fifties, passed over for promotion, he struggles to stay afloat until, nearly beaten to death, he's rescued by a monster. Unsure how to survive, he flounders in unfamiliar territory. Anger soon replaces what little fear the beast allows as Drew comprehends the fiend has no intention of releasing him. Both emotions quickly evaporate as he watches the bloodthirsty creature use men in a way. God, I want to be those men!
