Lots of emails from people asking me to comment on the JK Rowling/ Steve Vander Ark copyright case. My main reaction is, having read as much as I can about it, given the copyright grey zone it seems to exist in, is a “Well, if it was me, I’d probably be flattered”, but that obviously isn’t how J.K. Rowling feels. I can’t imagine myself trying to stop any of the unauthorised books that have come out about me or about things I’ve created over the years, and where possible I’ve tried to help, and even when I haven’t liked them I’ve shrugged and let it go.
