In April 2004, Barbara Egbert and Gary Chambers and their precocious 10-year-old daughter Mary embarked on a 2,650-mile hike from Mexico to Canada along the famed Pacific Crest Trail. Zero Days is a well-told tale of their epic adventure, which required love, perseverance, and the careful rationing of toilet paper. The trio weathered the heat of the Mojave, the jagged peaks of the Sierra, the rain of Oregon, and the final cold stretch through the Northern Cascades. They discovered which family values, from love and equality to thrift and cleanliness, could withstand a long, narrow trail and 137 nights together in a 6-by-8-foot tent. Filled with tidbits of wisdom, practical advice, and humor, this story will both entertain and inspire readers to dream about and plan their own epic journey. Six months later, Mary became the youngest person ever to successfully walk the entire trail.
