Query: good reading

After reading Black on Black I went to the local library and checked out the rest of K D's books. I think K D's books are very interesting and enjoyed Black on Black enough to order Space on Space ahead of time. Her Moonspeaker series and Imperium game were just as interesting and hard to put down. I compare her books favorably with the Pern series by MaCaffery.
