"It's off to the rescue when the Hotel Strange's ghostly concierge is arrested for not scaring people. Hardly are the dust bunnies and other residents of the Hotel Strange ('It's a little weird, but it's never boring') beginning to settle in for the winter than a pair of ghostly police officers whisk Mr. Snarf away. Setting off in pursuit, Marietta and Celestin―both light-skinned human children―along with Mr. Leclair, a dapper rat, and shaggy purple troublemaker Kiki are sucked up through a tornado to the cloudy Land of Ghosts. There, the law of the, er, land is 'It is forbidden.' But all is quickly and happily resolved, as Kiki moons a horrified crowd to get the rescuers thrown into jail with Mr. Snarf, and charges are dismissed once Mr. Leclair unsticks a page in the Rulebook of Ghosts to reveal Rule Rainbow: 'It is forbidden to forbid.' Aside from the children, everyone in Ferrier's neatly arranged sequential panels is an animal or some sort of (unscary) monster in human garb. A mouthwatering recipe for caramels at the end is but one reason young readers will want to check in to this series."―Kirkus Reviews
