Lost on Purpose is the nonfiction adventure narrative of a former technology executive who took leave of the real world to reinvent himself as a 21st-century mountain man. In October-November 2013, Patrick Taylor crossed the Rocky Mountains alone on foot. He passed through one of the largest wilderness areas in the lower 48 to reach and retrace the route of Lewis and Clark in the winter. The sacrifices – vocationally, financially, emotionally – are measured against the benefits by the author in a refreshingly honest, humorous, and inspirational fashion.
