Review # 1 was written on 2018-11-17 00:00:00 DON WILLIAMS A good beginning history of the Life of Thomas Jefferson. Very simple, well illustrated book. Tonya Dugan gave me this book and I have used it in the Classroom and when tutoring.

Review # 2 was written on 2010-01-26 00:00:00 Roger Wallen A good introductory biography for children as it tactfully handles some of the more risque or hypocritical issues of Jefferson's life. For example, it mentions Sally Hemings a few times, and also Maria Cosway, but doesn't bring up their alleged sexual relationships. In this way, it sets up a reasonable, foundational gateway for children to build upon when they are old enough to learn about such things. Ages: 7 - 11 Cleanliness: Mentions that Jefferson liked to flirt and dance. **Like my reviews? I also have hundreds of detailed reports that I offer too. These reports give a complete break-down of everything in the book, so you'll know just how clean it is or isn't. I also have Clean Guides (downloadable PDFs) which enable you to clean up your book before reading it! Visit my website: The Book Radar.
