OMG, I read every one of Mary Stewart's books back when I was a young teen and just getting into romance (too many years ago to count

). I've never reread because I've always been afraid they wouldn't hold up to my charmed memories, but maybe I should pick up a few.
As I recall, my favorites were The Moonspinners, My Brother Michael, and Airs Above the Ground because I was horse mad and that one was set around the Lipizzanner stallions in Austria.
