Caulborn Series by Nicholas Olivo

Vincent Corinthos has two things going for him: he’s a top operative of a secret agency tasked with handling paranormal threats, and he’s half-god. Normally that’s a combo that leaves him well-equipped to handle any problems that come his way. Until now. Something is snatching Boston’s most powerful paranormal entities right off the streets. Vampires, lycanthropes, fae, gremlins - no one is safe. No ransom notes, no bodies, no witnesses... moreVincent Corinthos has two things going for him: he’s a top operative of a secret agency tasked with handling paranormal threats, and he’s half-god.

With protective extradimensional barriers in place, Sakave’s attempted conquest is now little more than a note in the Caulborn’s archives.

Tapped for a black ops mission to repair the damage, Vincent finds himself under the command of a man who doesn’t trust him, and allied with an enemy he hasn’t seen in four hundred years. If they succeed, Earth and the Caulborn might pull through unscathed. If they fail, life as we know it ends. less
