Atlas Shrugged is a life changing book. I would also recommend “Unintended Consequences” by John Ross. It’s available as a PDF — I put it on my Kindle and couldn’t put it down. It really shows the tyranny of our government (and it was written before Obama).
These are just general reading suggestions, since I don't know where you are going and for what purpose; if you are venturing near Italy, try "THe Memoirs of Benvenuto Cellini", a landmark in the rise of human letters which details the life, work, and adventures of a true Renaissance man (and contemporary of Michelangelo and DaVinci, among others)
