This is a pretty good book, but I found it one of the weaker Pern books. It spans way too many years (about 27) and tells about things that that are in other books (Fax's death, Piemur's journey around the Southern Continent, and the stealing of Ramoth's queen egg, for instance). This wouldn't be a big problem because it gives these events from other people's perspectives, but there is a bigger problem. In the middle of the book, McCaffrey shifts from talking about Thella, Jayge, and Aramina, and instead talks about the Southern Continent and the discovery of Landing. If they would just stick to the renegades, it would have been a great book. On the plus side, the characters were wonderfully developed and it was nice to see Pern from the perspective of the ordinary people. But I'm afraid this is an example of a great idea being ruined by including too much and spanning too many years.
