The framework of "Rim to River: Looking Into the Heart of Arizona," published by University of Arizona Press, is a north-to-south trek author Tom Zoellner takes across our fair state on the Arizona Trail. Along the way, Zoellner (a former Phoenix New Times contributor) considers the history, culture, politics, food and geography of the state in his typically engaging style. The fifth-generation Arizonan blends affection for his homeland with clear-eyed consideration of its faults, and the result is a must-read book for anyone interested in the Grand Canyon State. Zoellner was the one walking, but he takes the reader along with him for the journey.
