GoneGod World - R. E. Vance - Bog

Welcome to the One Spire Inn, the only hotel in town that accepts fairy tale monsters as guests.
Can a retired monster-hunter and an inebriated fallen angel keep these new guests in line?
Jean-Luc Matthias promised to help these wayward mythical creatures... a promise he plans on keeping even if it figuratively or (the more probable option) literally kills him. Too bad he's a man of his word.
But preparing fae, succubi, poltergeists, and twice-fallen angels for mortal life is just the start of his problems.
A powerful demon is terrorizing the city. And what's worse, the creature's bloody deeds are exhuming Jean-Luc's past.
A past that could destroy everything he's built.
But if the creature isn't stopped, it might just trigger the apocalypse. Again.
Now Jean-Luc has a choice to make: Stay quiet and hope the storm blows over, or dust off his slayer instincts, thus risking everything and everyone.
