I would get this news at the library. Don’t want to break down and cry here. I loved her Dragonriders of Pern series, which I read as a teen. I am so sorry that she never saw the planned tv series come to fruition in her lifetime. An amazing fantasy writer, I think I still have my copies of her books. Her Web site is here. According to Locus Magazine she passed away yesterday:
SFWA Grand Master Anne McCaffrey, 85, died November 21, 2011 of a massive stroke at home in Ireland.
Goodbye, dear lady.
