A Hostage for Hinterland

Incredible cover art. Political intrigue mixed with science fiction. Amazingly this hasn't been dated as so many sci fi works from that period have become. Author also gives history throughout the novel making it believable. Have read it 30+ times since I read it first back in 1976. Sorry the author never wrote a sequel on life after the demise of the structures - or even novels about Union and Hinterland in earlier phases of the 1000 year structure history or - how about a novel about the covert mission of Rivera French into Hinterland years before? Arsen, if you're reading this, put the economic literature aside and consider it - it's never too late!!!
