Hmm. Possibly? I've read most of the books in that series, but I can't remember any based on The Nightingale. I might have read it and just forgotten it.

You probably already know this, but have you heard about the Coyote Road (http://www.amazon.com/exec/obidos/tg/detail/-/0670061948) anthology they have coming out in June? All stories about trickster characters; it made me think of you.
