Query: Impressive.

I have read a number of other great Artic stories (e.g., In the Land of White Death, Valerian Albanov). I would have to put this book on the top of my list.Somehow, even knowing how the story ends, I was spell bound by their trials and tribulations in their efforts to survive in the Artic. Jennifer Niven did a great job in careful re-creating the events in such detail that I felt I was there with them.
