Imperium Publisher's Summary

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. Rumors swirl about a secret project that's experimenting on paranormals. Then a fellow agent disappears and things get personal.

Aided by a new partner and a hyperactive gremlin with an appetite for junk food, Vincent must find the missing paranormals before everything he cares about falls under the control of Project Imperium.

    In 1854, Caulborn agents stopped an interdimensional warlord named Sakave from conquering our universe. With protective extradimensional barriers in place, Sakave's attempted conquest is now little more than a note in the Caulborn's archives. That is, until the recent catastrophe at Ashgate Penitentiary weakened those barriers and made Sakave a threat again. Things get worse when Commander Courageous gives Vincent Corinthos a dangerous piece of advice, which fractures those barriers even further.
