In early 2022, Walker set out to hike 600 miles along Siberia’s frozen rivers, hoping to better understand its indigenous peoples and how they reckon with their haunted past, and their future. So far, so intrepid. But after Russia launched its full-scale invasion of Ukraine, this compellingly written book charts how his adventure descended into a paranoid nightmare after he was arrested and imprisoned.
