Huntford's absorbing dual biography, revised and updated for this edition, is a rousing tale of hardship, technical challenge, political ambition, and fortitude. This is the still controversial book published 20 years ago that effectively de-constructs the much mythologized Robert Falcon Scott. Clearly an admirer of Amundsen, Huntford interweaves the story of the two expeditions, contrasting Amundsen's well planned campaign with the many follies of Scott's ill-fated quest.  (ANT100, $15.95)
