I had wanted to understand "the way things really are" as far as American History and my/our relationship to government. For instance, The US Constitution. Highly technical. What does it say? What does it mean? About 2 years ago, I came across a site ThinkorbeEaten.com. Look for the links to The Informer and James Montgomery, two historical researchers who cite their discoveries well. You'll never see the words democrat or republican here. I do have an audio cd of 20 hours of interviews with The Informer that have helped me in my understanding the way things really are. He does also cite really good sources of history that one can read. I have ordered several of these books from Amazon and also "the interlibrary loan system". You have stated you want the latest books but if you want to find out why things are the way they are today, I would suggest getting older history books. The older, the better. I will recommend three for now and some good sources for legal dictionaries that will help out in a big way.
"The American Admiralty" by Erastus C. Benedict. ( Considered by many to be the authority on Admiralty Law) "War Powers under the Constitution" by William Whiting ( Lincoln's Special War Counsel during the Civil War ). A History of the American Bar by Charles Warren.( Not a Law Book ) To get a good legal dictionary ( I bought Black's Law 8th ed from NYU bookstore, it's garbage compared to the one I recommend ), go to ConstitutionSociety.org and you can download Bouvier's 1856 legal dictionary(free).
I have many more cites if you want but you'll be busy if you follow up with these suggestions.
Happy to help, hope you'll be satisfied.
