Human in Equestria. You have been warned

Jim Butcher Single Line Synopsis (TM): When Daniel Travers is forced to stop an all-powerful reality warping dragon from unleashing hell on an unsuspecting Sugar Bowl of a world…AGAIN, he grits his teeth and steps up to do so. But WILL HE SUCCEED when no pony believes his tale and everything from a griffon army to the voices in his head are trying to kill him?

As an aside there will be both violence and romance in this story but hopefully not enough to need either the "sex" or "gore" tags.
