Here's what Anu wrote to me, Anna, when I asked whether he had any signed copies:
BTW, if you saw the book info on Amazon.com, it's old. The publisher is in process of having it updated on Amazon.com Web site. The cover has changed (it doesn't look so childish now) and the book is softcover, not hardcover.
(Between you and me, I think he's a little excited about it.)
