For a good audio book, try Limitations. It is a fast paced, thriller, with several sub plots, about the courts and the basis for its decisions, as well as what influences those legal decisions. The personalities of criminals and lawyers are explored. The plot unwinds slowly with many twists and turns and will hold your interest. It would be a good book for a plane flight, beach read or vacation and possibly for a book club since there are topics covered that would lend themselves to discussion: what causes criminality, is it rape if the woman is complicit but abused, are all punishments meted out fairly, how does personal life affect the decisions of judge, jury, lawyer, criminal? A philosophical discussion could really be even more interesting than the book itself which is interesting but not rocket science.
