Whatever I happen to feel regarding special editions, it is not within my power to prevent a publisher from selling those rights as they see fit. When it comes to the existence of special editions, however, it is important to remember that they exist alongside the "standard" editions of the work and readers are wholly within their rights to purchase or not purchase them as they please. As a point of principle, while special editions of my work may contain some minor customisation (e.g. a letter from the author) they will never contain anything vital to the story itself. The standard edition of the book will always be the whole and correct version of the text.
