Weighing in at over a thousand pages and a good two pounds (at least), this is purported to be the definitive one-volume biography of FDR. I truly hope so, for I don't believe my wrists could endure another paragraph on the subject. That being said, it is indeed comprehensive (perhaps overly so in some of the minutiae of policy-making). Black appears to have perused the memoirs of nearly every single individual who ever interacted with FDR. To someone as lamentably ignorant of history as myself, this book presents a number of captivating revelations that were never taught to us in high school: FDR's unsuccessful attempt to revamp and severely curtail the power of the Supreme Court; his shrewd and cynical handling of Joseph Kennedy, Douglas MacArthur, all of his vice-presidents, and countless others; Congress' refusal to permit absentee voting for American GIs during WWII, in part due to the fear of enfranchising black soldiers...
Black seems disinclined to recognize Russia's decisive role in defeating the Nazis. He even writes, \\"...the British and Americans could have defeated Germany without Russia, and would have done so, even without atomic weapons.\\" Hmmm. So while Black doesn't conceal FDR's less appealing traits, his insistence on the complete collapse of Western civilization as the inevitable consequence of continued American isolationism, a stance artfully undercut by Roosevelt, does impart a hint of hagiography to the book.
Overall, though, this is an outstanding overview of the man's life and times, with vivid depictions of his contemporaries (particularly, Churchill) and incisive analyses of the issues surrounding the Great Depression and the evolution of the war.
