Re: JCO: book signing
I've had multiple experiences at JCO's readings and appearances.
She will graciously sign up to 3 volumes, regardless of when they were published. The only restrictions put upon the signings are usually those of the hosts.
I think it's just a courtesy to purchase the book she's promoting and include it as one of the three.
First edition of Son of the Morning? Treasure it, as I'm certain you do.
