I remember when Janet Farrar was here a few years ago and I got to spend a bit of personal time with her (that was wonderful). I remember that she talked a lot about fae magic and encounters she and Stewart had back in Ireland, but I can't think of any books that deal specifically with the topic.
It's been a while since I've read it but I remember it very informative. What did I learn from it? Fae are too whimsical to work with but they are still worth knowing about. I wouldn't want to have one cross at me.
I have some stuff by her- pretty good, if I remember correctly. I don't necisarily want to work with them, but I would like to know more. And I definatly wouldn't want to cross most of the Faerie races.
