This is not a biography. This is a hagiography written in adulatory, reverential language that gets so worshipful in places that it becomes almost embarrassing to read. It’s more like reading a latter Ken Follett novel than a work of nonfiction. FDR is presented as the undisputed and indisputable hero, and everyone who disagrees with him is a nefarious villain. Everything is utterly one-sided with nothing within hailing distance of criticism or reflection presented.
If you are looking for an exceptionally long love letter to FDR, this book is for you. If you’re looking for a biography, it is not.
