This is the twelfth book I've read that covers some aspect of the Shackleton story (or stories, there were more than one expedition). With the knowledge gained and the information learned, I can get rid of the other eleven off my shelves. This edition is an excellent summary of them all, and contains a treasure trove of pictures, some of which aren't in the other books. For someone looking to learn about Shackleton, this is not the place to start, except as a quick overview. An excellent offering, great writing, superb photographs.
