In 1918 Wisconsin, 11-year-old Sterling North has an almost perfect life. He keeps skunks in the backyard, goes everywhere with his enormous Saint Bernard, and is building a canoe in the living room. The only trouble is life gets a little lonely for him and his father since his mother died. While scouting around the woods one afternoon, he discovers an abandoned, month-old raccoon.

The Magic Tree House transports Jack and Annie to the freezing Arctic where they must solve Morgan le Fay's final riddle in order to become master librarians. But it's not going to be easy — especially when they have cracking ice, a seal hunter, and a prodigious polar bear to deal with.
