We are right now in the middle of a long drive to Bryce Canyon and Zion National Parks. Dad has been talking about this “back to nature” trip for years. He says he’s been waiting until Morgan and I were old enough to really experience the wilderness. I guess at ten years old, we finally are . . . Join the Parkers, an intrepid family of four, as they embark on their first national park adventure. Twins James and Morgan explore the natural wonders of Bryce and Zion, journeying among the hoodoos and sleeping beneath the stars. But the trip takes a turn for the worst in the treacherous Zion Narrows—can they rescue Dad from a dangerous fall?
