Any good books on Thomas Jefferson?

I’m looking for one that is very readable; something that would give an insight to the human characteristics of Jefferson: his struggles with his faith, his good and his bad sides.

Any recommendations?

American Sphinx.

Thomas Jefferson: An Intimate History by Fawn Brodie.

My husband read this one and liked it, and I have enjoyed other books by Ellis.

I enjoyed it too, Ellis is a good read.
