I personally found this book to be a superior and well-written guide on the subject of desert travel and exploration. Far from being a generic book on the subject of surviving in a desert (actually, the SAS desert survival book comes to mind on that score), the Ultimate Desert Handbook is one of the few desert books I've found that actually attempts to address individual deserts of the world and their differing requirements - climates, geological construction, and specific hazards. This includes recognizing and avoiding venomous and biting reptiles and insects, heat and exposure dangers, navigation (including map, compass and GPS), clothing, equipment, water supply, rescue techniques, and first-aid and survival chapters that cover everything from poisonous lizards of Mexico to water-bearing plants in the Namib. It even contains valuable information on desert acclimatization and vehicle preparation. The Royal Geographic Society's desert exploration section must think it a good book as well, as it's on their recommended reading list!
