Set in Canada's Northwest Territories in the 1930s, Spirit Lights continues the adventures of twelve-year old Jean-Paul, his husky, Sasha, and Inuit friends he made in the first book, The Haunted Igloo. Returning to the Arctic after a two-year absence, Jean-Paul has overcome his fear of the dark, only to discover that his best friend Chinook is afraid of spirit lights. One dark polar night, after searching by dogsled for a crashed plane, Jean-Paul hears sounds that seem to come from an aurora. Chinook and their friend Kunee say the spirits in the lights are speaking, warning of danger, but Jean-Paul knows auroras can't talk . . .
