RaveThe Washington Independent Review of BooksThe writing is bright and engaging, borderline \'CSI\' thriller at times, like when he encounters a mysterious \'death assemblage\' of muskoxen frozen in ice. Berger has written a book about conservation, yes, but there is something here for every type of reader. Berger is a field biologist who aims to see the world from the perspective of the animals he studies ... The section on Bhutan is especially enjoyable, walking the line as the book often does between adventure tale and science writing ... This is not just a book for scientists or environmentalists, but feeling humans of all stripes ... This is a heavy yet humorous read of the most important kind. I challenge any reader capable of perspective and empathy not to feel inspired...and be spurred on to climate action by Berger’s vivid anecdotes of animals at the extreme edges of the world.
