Twisted Trails in Grand Canyon — Mary Morgan

Mystery, adventure, and a dangerous rescue await Ben and Bekka Cooper and their cousins, Kyla and Jack, at Grand Canyon's Phantom Ranch. The family reunion quickly turns into a weekend of thrills, chills, and a near spill over a cliff into the canyon below. But there's a sneaky thief. Who is it?
Twisted Trails in Grand Canyon gives young readers what they've come to expect from a National Park Mystery -- a book they can take to the park and live out.
