Unintended Consequences is a complex and lengthy book, the first part of which is probably the finest historical novel concerning the "gun culture" that has ever been written. As the book leaves the realm of fictionalized historic events (such as the Bonus Marchers -- very few kids today will have learned about that in school) and becomes a pro-gun fantasy in which our hero and his girlfriend and his other girlfriend strike righteous blows for freedom by making it look like Democrat politicians have been killed in homosexual trysts gone wrong (I am not making this up) it loses credibility and becomes less enjoyable.
There is, in fact, a rather bizarre sexual undercurrent to portions of the novel, either because Ross thought it would spice up the narrative or because he's a little out there himself. I found this a little distracting and didn't think it added to the book.
Overall it's an excellent novel and well worth reading.
