In George Turner's post apocalypitic world a platoon of Gone Time soldiers searching for a missing holo-star. Gone time refers to the that barbaric time (ie now) where man was generally thick, dull wasteful and brutal. As you may guess Turner uses the medium of scifi to have a real go at our wasteful economic policies and often savage social policies.
Any such critique obviously rests upon the author's alternative view seeming better and plausible - which it is!
I don't understand why his books are out of print and so little read, I found the basic storyline of the thriller that he hangs these ideas upon very gripping - so one could read it as a simple adventure tale or as a profound testament of our times and a great marker for utopian futures! Beats me why he doesn't outsell that crap 'Lord of the Rings/winnie-the-pooh-for-adults' stuff, still no accounting for taste huh....?
