The Hunter and The Cultist - The Eternal Love Series, #1

Gustav Markov is one of the best Rogue Hunters the Vampire Council has ever seen. But he's snide, sarcastic, and is by far the most infuriating man ever to walk the Earth. That changes when a mission puts him on the path of not only a fiend from his past but his Lifemate. Abel Simpson has never known a life outside The Willows. His faith has been shaken by the actions of those around him. But nothing has rocked him like the dark-haired man who walks into his life. Gustav and Abel find a connection neither man has ever felt before, and it seems almost perfect.
Until the specter from Gustav's past rears their head, intent on repeating history. Can Gustav and Abel stop this menace before another young life is destroyed? Or will more blood be spilled all in the name of family?
