RE Guy Gavriel Kay... have you tried "Lions of Al-Rassam"? That's my favorite for a number of reasons. Fionavar got a bit old, and much of it felt rather juvenile.
The others, aside from Nail Gaiman, I haven't read. I just recently read a Gaiman short story, "Troll Bridge", found in "Smoke and Mirrors." I often prefer short fiction to long, and I deem this to be one of the cleanest and best short stories I have ever read. It joins "Johnny Mnemonic" [Gibson] (the story, NOT the movie), "Neutron Star" [Niven], and maybe also "The Hero as Werwolf" [Gene Wolfe] in my short fiction favorites list.
Would you be interested in lj-friending me? We have a number of lj-friends in common, possibly some real-life ones as well. We have probably met in person, though I am not certain about that.
I saw you write yet another comment on a friend's lj entry (this time, angelbob) and wondered what you write in yours. Sometimes I write things that may be of interest to you in mine, and of course this would be a mutual sort of thing.
Whether or not, have a lovely day!
