Career woman. Single Mother. Superhero. Sherry Benning knew having a baby would change her life. She didn't know it would change the world. After running into first one and then another of her old foes on the same day, the Matriarch begins to fear she has stumbled into one of those plots where some evil mastermind throws a hero's entire rogues gallery at her. To all outward appearances, Leviathan City is a place where super-powered beings clash in the skies every ten minutes, but the reality is much stranger still: the next phase in human evolution has already begun, and these new mutants have chosen the Matriarch to be their protector-whether she wants to be or not!
