When Kieran Hollow gets grounded for drawing on the walls, his anger literally tears open a window to the Land of Monsters, a peppermint-scented world of grim reapers, gnomes, sand worms, and spells gone wrong. There he meets Lysander, a skeleton in a neon green robe, and the two quickly become friends as they leap into wild adventures.
As Kieran keeps slipping between home and the Land of Monsters, he's expected to pitch in, learn monster rules, and figure out why he smells like icy rain instead of peppermint. With every new job and mishap, Kieran discovers that being different might be the most powerful kind of magic there is.
