This book, as of 2016, hasn't been published yet (or even written?). So how can people have rated it? It's been promised by the author for 2 decades but never delivered.
I keep looking to see if book 5 has turned up, I would prefer if the author just said I am not going to write anymore in this series and put us out of the misery of waiting.
I've got married, had a daughter, put her through college, and retired waiting for this book.
It will never be published.
I can only hope that when Gerrold dies that there is a sympathetic editor someplace that Dan scrape all his notes together and publish something posthumously. I doubt if I'll be around to read it.
YOU KNOW, there hasn't been any news @ !! 25 years !! Maybe it's all just a "HALLUCINATION". with his mental history it would NOT be surprising. If David is offended he can e-mail me.
