Blood Falls. Warrior Mage Librarians, #1

Between strange cryptids, forgotten artifacts, and dangerous magic, a Warrior Mage Librarian's work is never done. Trevor is a soft-spoken historian with a talent for research and a tendency to overthink. Sister Margaret is a battle-hardened warrior who carries more weapons than most small armies. Together, they travel between hidden magical libraries, protecting ancient knowledge from demons, rogue mages, and anything else that slips through the cracks.
Then the cryptids step out of the shadows. When non-human magical beings reveal themselves to the mage world, Trevor and Sister Margaret are sent to a summit meant to establish peace. Instead, they uncover deep fractures within the Cryptid Collective - and a rising faction that sees humanity as a threat. What begins as diplomacy quickly escalates into something far more dangerous. Blood Falls is the first book in the Warrior Mage Librarians series - a dark epic urban fantasy of cryptid politics, secret alliances, and looming magical conflict.
