Anne McCaffrey wrote dozens and dozens of books. She is best known for her Dragonriders of Pern series, but she has written many other fascinating science fiction / fantasy novels.
I've read 47 of her novels and have another ten I haven't read yet. There are a few more on my wish list. After that, all that are left are her few novels involving cats, which I doubt I'll read. Ms. McCaffrey passed away and there won't be any more.
Her son, Todd, is continuing her Dragonriders books and they are good, but he doesn't quite have his mother's talent.
I'm so glad that about 10 years ago, I wrote away for a bookplate hand-signed by Anne McCaffrey. She sent me two. They are treasures to me and I haven't put them in a book yet. They are still in the envelope they came in, all the way from the Ireland.
