There is not much I can say that has not already been said about Chernow and about this instant classic book on Grant. I have read a handful of biographies on Grant and this one clearly is the best. Chernow's writing style is smooth yet detailed and it somehow doesn't feel like I just finished a book with almost 1000 pages of narrative text.
I think Chernow is fair in his praise and in his criticisms of Grant - especially in his personal life and in his Presidency. I think my only criticism of the book is that I think Chernow spent too much time discussing Grant's alcohol problems. I realize it is an important part of his story, but it felt to me like the author went back to it too often. Other than that, this book is one of the best.
