Book excerpt: A thrilling mystery set against a stark landscape and the inspiration of Nome's real-life dog hero, Balto. Twelve-year-old Tee has just moved to Nome, Alaska, with her writer father and sullen little brother, Jack. Jack isn't happy about the idea of living in the middle of nowhere, but Tee and her dog Henry are thrilled -- so much open space to run around and sniff! But on a walk near their new house, Henry spots something that has him seriously spooked. Tee sees a mysterious shadow, and it seems to be following them. Have they disturbed a restless spirit? And what other secrets might this dark place be holding?
