Through a decade of challenging hikes up Colorado's 14,000-foot peaks, the Fourteeners, with his father, Richard J. Foster, Nathan Foster navigated his twenties - finishing college, choosing a career, a possible cross-country move, the early years of marriage and a major personal crisis. Along the way he would discover the wisdom - and love - his father could offer him. Here is their story together. Includes an afterword by Richard J. Foster, author of Celebration of Discipline and coauthor of Longing for God.
