One thing I like about collections like this is reading what the authors have to say about the stories, and Shiner says he likes that, too. So he includes notes about each one at the end of the book.
I haven't seen Lew in years, but I met him long ago at an AggieCon, and I remember sitting in the usual spot in the Memorial Student Center one night when he was talking about writing "Steam Engine Time." I like to think that I made a small contribution to that one. But don't let that stop you. Get this book while it's still available.
