One of the stars of science fiction, SFWA Grand Master Anne McCaffrey, died yesterday, age 85. Other websites will have thorough obituaries. Here I can point to a letter that I transcribed to this website a few months back.
In the letter the literary agent Virginia Kidd provides a deft critique of McCaffrey's writing at a crucial early point in McCaffrey's career. Read the letter.
On a personal note: I encountered the first two books in the Dragonriders of Pern series (the next books were years away from being published) at an impressionable age. The 14-year-old in me loves those books.
