I never read this when it came out. Can't think why, just missed it somehow. Reading the contemporary reviews and blurbs for it (in the 1980s) one sees how much of-its-time it was and so, may be now becoming only of interest to the readers of SF who deal in the historical context of works and how they code the time they were written in.

I'm sure my 20something self would have loved it, but the 40something self finds it to worthy to read now. (But I did finish it.)
