Just when you thought there was nothing left for Ayla to invent, she went and invented monogamy.Was that really what the entire series was leading up to? Sorry, but I was very disappointed. It didn't feel like the ending of anything, but I don't know if I could make it through another book. It was long and repetitive and boring and tedious and repetitive. Maybe some of it was me, after going back and reading reviews of the other books, it seems like the other books were repetitive and poorly written as well. I really liked the other books at the time and was looking forward to this one, but I read the first three in 1989 and the other two soon after they were released. I've read so much since then, maybe I just no longer have the patience for this type of book. There were no surprises, nothing you couldn't guess from reading the previous books. Nothing really happened, there was no story telling, she just explained everything in grave detail. I won this book through the goodreads first-reads program. It is an uncorrected proof and goodreads is mentioned in the publicity information inside the back cover.
