Too simple
Format: Kindle
Some of the information is inaccurate or out of date such as the food pyramid. Much of should have been learned long before they are ready to leave home. But some of it such as the simple recipes and the cleaning solutions are useful. I wish the author had spent a little time to address teens with disabilities and other special circumstances. All in all a decent book but the author could have done so much more.

Clyburn captures the past to warn us about the present and future.
Format: Hardcover
I enjoy this book. The history of white Conservatives first taking the black vote away by domestic terrorism and violence and then changing the rules to make getting the vote back nearly impossible explains the 70 year gap between the first eight and the ninth (Clyburn). He mixes the past record of lying and dirty tricks of Conservatives with current events that attempt to bring about the same result. Thanks for all of your work in bringing this great history. It should admonish all of us to work to make sure we don't fall victim to the lying and dirty tricks of the Conservatives of the present.
