It began with a simple question: "One day I found myself asking my father, across the chasm between us, 'Hey Dad, you want to climb the highest mountain in Colorado?'" And for Nathan Foster and his father, Richard, that simple question changed everything. With no hiking experience to draw on, they embarked on a journey of physical challenge, discovering just how far they could push themselves. For Nathan a parallel journey took him inside himself. Having grown up in the shadow of a famous father, Richard J. Foster, author of Celebration of Discipline, Nathan had a lot of questions about who his father really was. Would hiking open the door for him to get to know this distant figure? As the one-time experiment evolved into a decade of challenging hikes up Colorado's 14,000-foot peaks, the Fourteeners, Nathan 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 exactly what his father could offer him. This book also includes an afterword by Richard J. Foster, author of Celebration of Discipline and coauthor of Longing for God.
