A few days ago, fantasy author Terry Pratchett announced some sad news on Josh Kirby’s blog (in a post titled “An Embuggerance”). Apparently he has been diagnosed with a rare, early onset form of Alzheimer’s. His blog post sounds optimistic under the circumstances:

Folks, I would have liked to keep this one quiet for a little while, but because of upcoming conventions and of course the need to keep my publishers informed, it seems to me unfair to withhold the news. I have been diagnosed with a very rare form of early onset Alzheimer's, which lay behind this year's phantom "stroke". We are taking it fairly philosophically down here and possibly with a mild optimism. For now work is continuing on the completion of Nation and the basic notes are already being laid down for Unseen Academicals. All other things being equal, I expect to meet most current and, as far as possible, future commitments but will discuss things with the various organisers. Frankly, I would prefer it if people kept things cheerful, because I think there's time for at least a few more books yet :o) Terry Pratchett PS I would just like to draw attention to everyone reading the above that this should be interpreted as 'I am not dead'. I will, of course, be dead at some future point, as will everybody else. For me, this maybe further off than you think - it's too soon to tell. I know it's a very human thing to say "Is there anything I can do", but in this case I would only entertain offers from very high-end experts in brain chemistry.

Terry Pratchett has been one of my favorite authors ever since I first discovered his Discworld series about 20 years ago, and his cheerful satirism has made my life richer numerous times. I wish him all the best and sincerely hope he pulls through this.
