Mystic Passage. His Name Was Augustin, #2

"You fool. You have known the glory of the Teuton priest. For the rest of your life, you will want a priest. There is no hope for you now." Can't say I expected this. All I wanted was to take a quick trip to medieval Europe to witness the fall of the Teutons, but a band of warriors attacked me and my travel buddies minutes after we got here. One of them murdered my cousin, and now her boyfriend Joel is heartbroken.
And if that wasn't bad enough, we've lost the power to open time's gateway. That means we're trapped here, a thousand years in the past. Now Joel and I have to assimilate with people who sneer at outsiders. They're suspicious of me, too. Well, most of them are. The city archivist, Augustin von Bayern, has offered to teach me the darker side of magic. Of course he's the handsomest man in town-and his intelligence tantalizes me in ways I've never known.
I guess if I'm stuck in the past, I might as well go all in, right? But it just so happens that Augustin worships a demon in his spare time .
