Don't Fear the Reaper - J. C. Murphey - Bog

Life as a college student is hard. It's even harder for Victor Rexford when a cult brings about the end of days via a botched summoning, and he happens to be in the wrong place at the wrong time. Fortunately-or maybe unfortunately-Victor catches the eye of the Grim Reaper during this particular ritual, becoming further embroiled in an epic fight between supernatural entities. She needs him as a host to remain on Earth to exorcise the demons, and he needs to grow a spine.
Over 100 years later, the world is an apocalyptic wasteland filled with humans possessed by demons and mutated into monstrous forms. Vincent, one of the few remaining mortal humans, is sent out by his father and camp leader to find others to" join his flock." Instead, Vincent sets his eyes to the north of their humble camp in old Pennsylvania, following an irresistible pull.
What is he searching for? Who is calling to him from every shadow? And why is she so... sad?
Vincent will find that Death is not always the end.
