I'm sorry, it's all my fault. CSB inbound:
Several years back, I took my wife to a signing for Feast for Crows at the (now gone) World's Biggest Bookstore in Toronto.
The info said he'd sign anything he'd written, and I happened to have the first Wild Cards volume, so I grabbed it and off we went.
Well, when we got to the table, he seemed surprised to see it, and said something like 'Ah, that takes me back.'
A month later, he announced a ton of new Wild Cards stuff. So I think it might be my fault. Sorry.
