Deviant-Hunter's Sabbath (Eve of Light: Deviant-Hunter, #3)

Frank Sanders has spilled a lot of blood over the years. He is neither proud nor apologetic. The human population is under assault, engaged in a near-invisible war of which few are even aware. As a single father raising a young daughter in a world where viral terrorists with supernatural abilities are ascendant, he has had no choice but to make sacrifices anything and everything to make the world a brighter place for his only child. He has always assumed one day he'd have to make the ultimate sacrifice. . . But when that dark day finally comes, what he is called to do is far more dreadful than anything he's ever imagined.

A gritty Dark Metaphysical Fantasy.
