I enjoyed this book better than the first. Maybe it's the development of the story, or just revisiting an incredible alternative world. Harrison is a master storyteller and the concept of dinosaurs not going extinct, and making slaves of humans, is mind-boggling. Like other readers, I wish the series were longer.
Happily, I have found another series that is remarkably similar: the Dinosaur Wars series byThomas Hopp. Written recently, they have one advantage over the Eden books. The intelligent human-sized dinosaurs are feathered and bird-like. This is more realistic according to modern science, but Harrison couldn't have known what would later be discovered in China while he was writing of scaly, almost amphibian dinosaurs in these books. Ah, well, everything evolves, including our view of what an intelligent dinosaur might be like. Also, Hopp writes of dinosaurs returning to the present-day world we live in, not an alternative. So there are some cool tank battles and cruise missile counterattacks. Again, an evolution of Harrison's concept.
Hooray for both authors. Long live the subgenre!
