Blood Falls — Anna McCluskey

IQBetween strange cryptids, forgotten artifacts, and dangerous magics, a Warrior Mage Librarian's work is never done. Trevor and Sister Margaret might seem like an odd pairing. He's a mild-mannered historian with a wry sense of humor and she curses like a sailor and carries an arsenal of weapons everywhere she goes. But they're fast becoming one of the Vatican's best teams of Warrior Mage Librarians -- mages who travel between remote secret libraries, defending them from accidentally-summoned demons, mages with ill intent, and other threats. Then cryptids suddenly reveal their existence to the human mage world and everything changes. Sister Margaret and Trevor are sent as emissaries to the annual summit of the Cryptid Collective, where they find that not all cryptids want mages around. And some of them want to wipe humanity from the earth altogether. Will Trevor and Sister Margaret be able to root out the enemies of humanity? Or will the world be plunged into a war like nothing it's ever seen before?
