Jill Homer has an outlandish ambition: Racing a mountain bike 2,740 miles from Canada to Mexico along the Continental Divide. But her dream starts to unravel the minute she sets it in motion. An accident on the Iditarod Trail results in serious frostbite. She struggles with painful recovery and growing uncertainties. Then, just two days before their departure, her boyfriend ends their eight-year relationship, dismantling everything Jill thought she knew about life, love and her identity. This is the story of an adventure driven relentlessly forward as foundations crumble. During her record-breaking ride in the 2009 Tour Divide, Jill battles a torrent of anger, self-doubt, fatigue, loneliness, pain, grief, bicycle failures, crashes and violent storms. Each night, she collapses under the crushing effort of this savage new way of life. And every morning, she picks up the pieces and strikes out to find what lies on the other side of the Divide: Astonishing beauty, unconditional kindness, and boundless strength.
