Mount Olympus is preparing for the arrival of some special guests: the mighty gods from Asgard in the North. And it seems that Odin, the ruler of the Asgardians, has an important mission for Demon. Goldbristle, the gods' prized shining boar, is losing his light. Now Demon must travel north and search this cold, snowy land for anything that might cure him. The latest installment in this chapter book series by Lucy Coats blends elements of mythology, fantasy, animals, and adventure with plenty of humor and heart.
