Guy emailed me last week, pointing out that the rights to The Fionavar Tapestry were held by HarperCollins, not Penguin Books. Hence, it did appear that his first trilogy wasn't part of the backlist which constitutes the prize of this contest.
Well, I'm happy to report that The Fionavar Tapestry will be part of the prize. HarperCollins just got back to me and they have accepted to supply the trilogy.
Many thanks again to the folks at both Penguin Books Canada and HarperCollins Canada for their support. Everyone has time to register for this contest, as the winner will be announced in early January.
Best of luck to all the participants!:-)
