The Plot Against America by Phillip RothRead about the other entries on the list.
Another alt-history novel, Roth's book envisions a world where Charles Lindbergh defeats FDR for re-election and may or may not be a Nazi puppet (but is definitely a Nazi sympathizer). It also features Walter Winchell leading an anti-Lindbergh movement and being assassinated by a possible American Nazi, with KKK help. Then there's a coup by the Vice President and history righting itself at Pearl Harbor. And then there's the German propaganda blaming a Jewish conspiracy for Lindbergh's disappearance and the Lindbergh baby kidnapping -- versus the reigning conspiracy theory that the Nazis were behind everything.
The Plot Against America appears on Steven Amsterdam's list of five top books on worry, Stephen L. Carter's list of five top presidential thrillers, and David Daw's list of five American presidents in alternate history.
