Jill wasn't an athlete, at least not in the more insecure corners of her identity. What she was, was cold. And frightened. And alone in the frozen wilderness of Alaska, more than a hundred miles from the nearest outpost of civilization. As she struggled to maintain forward motion, she couldn't help but strive to piece together the reasons that brought her here in the first place, to the Iditarod Trail, with nothing more than a bicycle and a few essential pieces of gear, in February. What possessed her, a timid Mormon girl from the suburbs of Salt Lake City, to sign up for a 350-mile bicycle race across frozen Alaska? How was she possible going to survive, let alone finish, this grueling adventure through the heart of her deepest fears? She muddled for answers from the wind, the mountains, the tundra, the faint trail she followed, and the ghostly trails of her memories.
