When 25-year-old Jasper McKenna is torn from modern Earth and thrust through a portal, he lands at the gates of a fortress straight out of legend—just in time to fight for his life. His unlikely victory over a cruel noble crowns him the new Lord of Castle Tower, but Jasper soon learns that wielding power in this strange medieval world demands far more than a sharp blade.

Armed with nothing but a modern understanding of how a castle should run and a bit of determination, he begins reshaping his new domain with fairness, innovation, and compassion. To the astonishment of the castle’s weary staff, their new lord proves generous instead of greedy, principled instead of proud. As Jasper rebuilds trust, rekindles trade with neighboring realms, and earns the loyalty of those who once feared their rulers, he discovers that monsters come in many forms—and not all can be slain with steel. In a land where danger and intrigue lurk behind every banner, Jasper must prove that integrity is the strongest weapon of all.
