I've never read anything by her, but I recognize the name as well as I recognize the name of Robert A. Heinlein or Ursula K. Le Guin. For some reason, I just haven't bothered to read anything by her.
But that's going to change. I, too, would like to know which ONE ebook is the one to buy.
By the way, here's a link to TOR on her:
