I am a law practitioner in Romania, and I would very much enjoy to start reading about the U.S. Legal System.
I thought that a good place to start would be a book on the general theory of law, so that I could understand the principles, the judicial system, important institutions in private and public law.
My area of practice is Civil Law, so if you could recommend a (university) book on the general theory of civil law, I would be very grateful.
I'm not familiar with how courses are structured in the U.S., so, for example, a general theory of civil law course at Romanian Universities contains information such as principles, source of law, a short introduction to the judicial system, definitions of general concepts such as civil rights and obligations, and a short trip throughout all civil institutions - persons, obligations, contracts, successions.
Of course, introduction in criminal law books are welcome.
I am open for any suggestions. If the authors are well-known, the better.
