It is a book which could be compared to Chatwin's The Songlines for its combination of travelogue and poetic vision. Yet the beauty of the prose and the thought-provoking evocations of modern culture's shifting relationship with the environment are in a league of their own. Here are sparkling descriptions of the lives of caribou, muskoxen, polar bears and narwhals, and extraordinarily moving passages which meditate on the nature of our relationship with the world, the inter-dependence of ideas, desire and science and the possibility of dignity and compassion in the contemporary world.

It is a measure of the respect which Lopez has for his subject that his book exemplifies the supreme importance which he ascribes to the ethics of respect in the face of all existential paradox:

"There are simply no answers to some of the great pressing questions. You continue to live them out, making your life a worthy expression of a leaning into the light".
