Query: Grant and Twain through Amazon's books

Admittedly I am very fond of Ulysses Grant. He loved and married one of my great great aunts. And I am pretty nuts about Twain too. So it was a wonderful surprise that this book was very interesting, well written, and a wonderful read. I knew something of the subject before hand, but I am so glad I found this book in Amazon's book list, and it was so easily found and obtained. Three cheers for General Grant, Mark Twain and Amazon!!!
