The last good one was James Madison and the Struggle For the Bill of Rights by Richard Lubunski.
I started Thomas Jefferson: Secrets at Monticello and it was a bunch of tabloid/gossip rubbish!
I have the book Jefferson- Writings: Autobiography, Notes on the State of Virginia, Public and Private Papers, etc. It is a Library of America book. I confess I haven’t read it cover to cover. I do pick it up every once in a while and read some of it, I have learned a lot of things I didn’t know before. There is a lot of detail about things that happened during his life. Very interesting.
Pick up Thomas Jefferson: A Life by Willard Sterne Randall (1993)
Well worth it
