Query: Disappointed...

As a fan who has been enjoying McCaffrey's stories for over 10 years, I found this book to be far below what I've come to expect from her writing. The various series she has published - from Pern, The Rowan, Crystal Singer, Dinasour Planet, even Freedom and Brain Ships - are all well written and utilize a similar style and level of competence. The stories on Acorna, however, seem to be written by someone else entirely (her son, perhaps?). I don't know how to describe it other than by saying it is far below her usual standards, with childish dialogue, nonexistant plot, and flat characters. If you don't like this book, don't give up on her; go read one of her other series (Dragonsinger is a great intro to the world of Pern), because she really is a talented writer.
