The best of the Teddy Roosevelt trilogy was Theodore Rex, followed by teh first book. I found the final book, Colonel Roosevelt really dragged when it got bogged down in the 1912 race and the building of the Progressive Party.
I want to read American Sphinx, about Thomas Jefferson and a similar history book, but not Presidential that was OUTSTANDING was Undaunted Courage, about the Lewis and Clark expedition.
Not actual non-fiction, but a great read on the founding fathers was Burr by Gore Vidal. Definitely a book with a point of view, but a very interesting take.
