For Pittsburgh, it would be Mysteries of Pittsburgh: A Novel (P.S.). I met Michael Chabon 20 years ago (how time flies!) back when I was just impressed to even be in the same room with someone who was published. (This event looms large in my life - not so large in his.)
And for Portland it would be Katherine Dunn’s Geek Love: A Novel. I met her at Wordstock in 2009. She said she was an admirer of mine. I have no idea what that meant - it could even have referred to my newspaper reviews - but the for the next two weeks I walked around on a cloud.
