When a group of Nationalists use an ancient artifact to bring a villain from Arthurian myth back from the dead to gain power, ex-monster hunter Bridgette McGuire escapes her retirement home and pulls her unsuspecting grandson Duncan, a museum curator, into a world of magic and mysticism to defeat a legendary threat.
What happens when the fabled sword appears, but no one is able to pull it out? Is this peace finally the result of so many hard-fought battles?
Perhaps, but an unexpected claim to the throne is lurking, closer than Bridgette and Duncan can imagine.
