Soft five stars. Obviously, most of the jurisprudence went way over my head, and yet the description of the intent, clarifications, and examples made the book a great read still. It was also great to see familiar terms such as 144A and RegS, as well as connect the 80s and 90s financial shenanigans with the resulting laws (Enron-WorldCom-Arthur Anderson, Merrill Lynch, and Internet stocks abound). Also, this is obviously not a judgment on the soundness of the laws themselves. Even there, the book sometimes pulls no punches in commenting on moments of overreacting (thereafter putting up a virtual shrug and saying "well them's the law"). A surprisingly good casual read, so long as you have some patience over the jurisprudence.
A little dry, but lines like: "you should not become exasperated by the lack of clear lines and tidy categories. The elusive search for 'security' is a wonderful, if challenging, amusement." - make it all worthwhile. Honestly, this was good review material for the Cox, Hillman, Langevoort text.
