The Girl Who Loved Tom Gordon by Stephen King (Paperback)

On a six-mile hike on the Maine-New Hampshire branch of the Appalachian Trail, nine-year-old Trisha McFarland quickly tires of the constant bickering between her older brother, Pete, and her recently divorced mother. But when she wanders off by herself and then tries to catch up by attempting a shortcut, she becomes lost in a wilderness maze full of peril and terror.
