Having already surmounted K2 and Kilimanjaro, Rick Ridgeway set himself a very different sort of challenge—to find the calving grounds of the chiru, an endangered Tibetan antelope. As he recounts in this 2004 memoir, it is a particularly difficult journey; with three companions, Ridgeway made a 275-mile trek through the remote and vast region known as the Chang Tang, an excursion that will test their strength and skills to the limit.

"Ridgeway crafts an urgent, poetic narrative…. [He] also offers a thoughtful regional history and an affecting description of the complex human struggle surrounding the rampant poaching of chiru."—Publishers Weekly
