The book is an interesting collection of anecdotes, history, natural history and reflections on seven animal species living in the far north. Some of the chapters, like the one on polar bears, happened to contain mostly information which I already knew, and so were not so interesting, others (like the one on giant red king crabs) were about animals that I hadn't even heard of and so were fascinating.
The book is easy to read, with the chapters being split into small sections, some very small. It does jump around a bit from history to anecdote to biology, but that is not really a problem. Because of that, this is more of a book to read a bit at a time, than to sit and plough through in a few long sessions.
