We would always recommend a Friedman book for summer reading. So check out his page and look at getting one for the summer. Here is a good one to start with:
"Freedom is never more than one generation away from extinction. We didn't pass it to our children in the bloodstream. It must be fought for, protected, and handed on for them to do the same, or one day we will spend our sunset years telling our children and our children's children what it was once like in the United States where men were free." - President Ronald Reagan
