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. Bestselling writer Kieron Gillen (The Wicked + The Divine, Star Wars) and Russ Manning Award-winning artist Dan Mora (Buffy The Vampire Slayer, Klaus) explore the mysteries of the past, the complicated truths of our history and the power of family to save the day…especially if that family has secret bunkers of ancient weapons and decades of experience hunting the greatest monsters in Britain’s history!
