The secret war to prevent Cthulhu's rise has not gone well for AEGIS since the Herald's first and second plagues consolidated Richard Enfield's power in America. Deep under Brooklyn, the Crimson Brotherhood's Rat Queen prepares an army of otherworldly rodents to decimate the Big Apple. Before more reanimated horrors can be released, Shoshanna and Adam head to New York to team up with two unlikely heroes, the fiendish inventor Dr. Krull and a rat catcher named Lorenzo, to save the City that Never Sleeps from an eternal nightmare in The Plague of Mischief, the fifth book in Luellen's Magicae supernatural thriller series.
