What if dinosaurs had not become extinct, but instead evolved sentience? These sentient dinosaurs have also developed biotech to a certain extent, using non-sentient dinosaur species for various purposes. In the trilogy, the dinosaur civilization founds a colony in America and comes into contact with Stone Age humans. This whole thing could rapidly have descended into sillyness but it is mildly entertaining and thought provoking. The three novels are:
SciFi humor. I quite enjoyed the first five books or so, but in the end the laughter starts wearing thin. I gave up after “The Stainless Steel Rat Goes to Hell”. Those I have read are:
Golden Age style space opera about… You guessed it! A Plague! From Space! Actually, the novel is quite enjoyable even though it is far from deep and epic.
Novel set in a world (well, New York …) which is severely overpopulated. As a result, there is starvation, tiny living space, and general crappiness for the growing group of poor. It is set in the year 2000, but that is forgivable. A decent yarn and the basis for the movie Soylent Green.
