I have every one of her books in the Dragonriders of Pern series, and I think I have all of her son's, too. As well as the Rowan series, the series about the terraformed planet that woke up to be sentient, and the series about the mercenaries from a heavy-gravity planet who kidnapped Earthlings (and beings from other plants) and used them to colonize other worlds.
She was prolific, and she was readable. I started reading the Pern series almost thirty years ago. I'm sure I've read each and every one of them at least five times. I kept waiting for Hollyweird to turn it into a movie (or three), but it never happened. I even had it casted -- although due to the passage of time I'd have to start over today. My choices "back then" were:
F'lar - Tom Selleck
Lessa - Leslie Anne Warren
F'nor - Sam Elliott
Fandarel (the Mastersmith) - Hulk Hogan
Robinton (the Masterharper) - Kenny Rogers
Mennoly - Mary Chapin Carpenter
Anne's son, Todd, has now written three (or maybe four) books that continue the Pern legacy. His books are good, but (as might be expected from a computer professional) they take a somewhat more technical approach and are not as oriented toward constructing entire societies. In that he is blessed by the fact that his mother had already pretty well fleshed out the Pernese society long before she turned over the reins to Todd.
Heck, I even had Restoree, the book shown in the article. I'm sure it's here in the house, somewhere, but it wandered away from the McCaffrey dedicated shelves and has been AWOL for a protracted time.
R.I.P. Annie.
