In the first volume of this new middle-grade series, Drew Weing delivers a fresh and funny take on the age-old battle between kids and closet-dwelling monsters. Charles wasn't too crazy about moving to a dilapidated apartment building in Echo City, and that was before he learned that it was teeming with monsters! It's a good thing the kids of Echo City have Margo Maloo, monster mediator. Using her expertise with trolls, ghosts, and vampires, Margo brokers a fragile peace between the monsters and kids. An avid blogger, Charles has stumbled onto the story of the century! Margo has sworn him to secrecy, but she doesn't mind him tagging along on her latest assignment.
