Wasn't my favorite of the series, mainly because Perry's corruption wasn't very convincing and because it seemed a bit rushed in places. I mean, the other books covered no more than a generation or two, and this one covers at least 800 years, so I guess it's no wonder it seemed rushed. Also, Orb's suddenly deciding she does love Perry was not convincing. I suppose this is because the reader is supposed to have read "Being a Green Mother" first, but it was still not good. 
 Those are my complaints. Don't get me wrong, it was a very good book otherwise.
