Hob, an invisible house spirit who works hard for his family, even though they don't know he is there. "Hob's work is putting little things right, like folding away trampled thoughts, mending arguments, drying up spilt tears, unkicking bruises, or unscorching the milk pan." In this second adventure, a peddler sells Hob to a new-and seemingly perfect-family. But Hob soon discovers a huge, horrible secret living in their pond. Accustomed to smaller, domestic problems, Bog must use every ounce of his power and wit to prevent the giant catastrophe looming ahead. This novel combines comedy and tragedy, humor and pathos, with the bewitching elegance found only in the very best of children's fantasies.
