Jo Sherman IS the Fantasy and Science Fiction author. I go to cons, when I can afford it, like a lot of us folkies, and I met her at Ad Astra, the Toronto con. We've had some nice talks on the subject of folklore. While I'm sure she likes to meet a nice, fawning fan, she is also pleased to meet another folklore enthusiast.
Oh! Her book about the Babylonian demon in New York is pretty good
