I don't actually have a Naomi Novik book autographed. She was promoting
_Uprooted_, a YA-ish fairy tale type of novel. She wrote the Temeraire
series, SF stories about the Napoleonic wars, with dragons. She
autographed a mug for me.
JMS was promoting his memoir, _Becoming Superman._ (Quite the tale,
that one.)
I've heard that Orson Scott Card is a piece of work. My son, who loved
the Ender stories, was disappointed in him.
