The star review is for the edition only (I'm not sure I had the specific edition listed here, but it was definitely a Stanford Travel Classic edition).

The story is, of course, an amazing epic of survival in incredibly harsh conditions. Stars all round. However, the edition I read had no maps whatsoever, aside from a crappy representation of Antarctica on the cover. Having no maps makes a book like this so much more difficult to follow--half the events refer specifically to directions, geography and latitude/longitude. A map is even more crucial when these events take place in a part of the world which most readers are only vaguely familiar with. So that was very annoying. Don't buy the Stanford Classic version, I suppose.
