Query: Thomas Jefferson: A Life (Paperback)

OUCH!This was a really tough read.I had to read paragraphs sometimes 2 or 3 times as the context was very bland.A lot of information to be sure, but its presentation is less than stellar.Of the first 8 presidents I have read, this book took a couple years off of my life.Not nearly enough about his presidency or his politics in general.I would recommend another book on Jefferson, although I couldn't tell you what one.
