I don't have a right to read future books by you, no-one does, but selfishly I want you to continue writing. You manage to write fantasy that I want to read, that is gripping story, with people I care about, but that also has intelligent political thought in it, and that's a rare thing.

And, apart from that, you're a friend who I deeply respect, for all the things you've done over the years. I think it's significant that there are a lot of people who are definitely not insignificant who agree, as shown by the comments here.
