The authors have produced an extremely important book that raises questions of presidential accountability that remain unanswered today. Their work is meticulously researched and their conclusions fair, balanced and well-reasoned. It is hard to fathom how a life so completely and comprehensively examined as FDR's can still yield startling secrets nearly 70 years after his death. This work sheds an entirely new light on the character and motivations of FDR, as well as those of his inner circle of advisers and family. There is much here to ignite new debates of about how much the American people should know about their President's health and at what point that person should be considered incapacitated and how that determination should be made and - then what? A fascinating, well-written and apolitical book. Most highly recommended.
