The heroism of British explorer Ernest ShackletonDbest known for his failed 1914 Antarctic expedition in which he saved his 27-member crew from perishing under harrowing conditions for more than two yearsDhas been chronicled in numerous narrative accounts and, most recently, became the inspiration for another book of business nostrums, Leading at the Edge (Forecasts, Apr. 3). Although they tread in that book's footsteps, Morrell (a financial expert who has studied Shackleton's life and leadership style for 15 years) and Capparell (a Wall St. Journal business editor) have produced a first-rate business primer. With the help of diaries and other first-hand accounts, they vividly describe Shackleton's expeditions and his powerful leadership style, relating them to today's business world in a streamlined presentation. The authors also include the insights of a handful of modern-day leaders, including James Cramer, who believes that his own following of Shackleton's example in hiring talented, optimistic people made the difference for him at the TheStreet.com. Morrell and Capparell's book is strongest in its emphasis on leading a team against desperate odds over an extended period of time (""Give your staff an occasional reality check to keep them on course. After a time, people will start to treat a crisis situation as business as usual and lose their focus""). (Jan.) Forecast: With a first serial in the Wall Street Journal and a five-city author tour, this solid book may come from behind to overtake its competition, Leading at the Edge.
