Spark is not your average teddy bear. She’s soft and cuddly, sure, but she’s also a fierce warrior. At night she fulfills her sacred duty: to protect the household from monsters. But Spark’s owner Loretta is growing up and thinks she doesn’t need her old teddy anymore. When a monster unlike any other descends on the quiet home, everything changes. Children are going missing, and the monster wants Loretta next. Only Spark can stop it. She must call upon the ancient League of Ursus—a secret alliance of teddy bears who are pledged to protect their human friends. Together with an Amazonprincess doll and a timid sock monkey, the bears are all that stands between our world and the one that lies beneath. It will be a heroic chapter in the history of the League . . . if the bears live to tell the tale.
