With a contemplative tone, the author (In the Shadow of the Sabertooth, 2013) reflects on solo trips as well as adventures with his friends and family. Peacock's descriptions--whether of exploring the ranges and valleys of the Sonoran Desert, floating and fishing in a river in Montana, or studying grizzlies in Yellowstone and tigers in Siberia--are detailed and vivid, immersing the reader in the experience. Glimpses of his personal life, from preparing a meal for the memorial of his friend Edward Abbey to canoeing the Shiawassee River to repatriate Indigenous artifacts he collected as a child, offer insights. Also woven through the text is the importance of spending time in the wilderness, whether it is to deal with grief, to sleep well, or to hide out from the FBI for a bit. Peacock's concern for wilderness and its inhabitants is clear as he discusses climate change and its impact on habitats and the diminishing wild spaces around the world. His passion for the subject and his compelling writing make for a captivating and thought-provoking read.
