A period piece but still a good read
1970s Sci-Fi/action-adventure story with a novel premise. There's a small amount of Libertarian social thought being advocated, but while noticeable if you have an eye for such things (lots of science fiction can be as much about social issues as technological ones) it does not overwhelm. I have been looking for the original and not the series version for a long time, so I was very happy with this purchase. John M
