I love just about everything DiscWorld. One of the first books my husband and I bonded over was The Color of Magic, and we've been following the adventures of Rincewind, Nanny Ogg, Granny Weatherwax et al of Ankh Morpork and the surrounding kingdoms ever since. So when my husband told me this morning that Terry Pratchett had been diagnosed with a rare form of early onset Alzheimer's, I was absolutely shocked. The man has always been a comic genius as far as I'm concerned, and if you've never read a book by him then you've missed out on quite an adventure.
Here's the post Mr. Pratchett put up on his artist's website, http://www.paulkidby.com/news/index.html :

PS I would just like to draw attention to everyone reading the above that this shouldbe interpreted as 'I am not dead'. I will, of course, be dead at some future point, aswill 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.
Now I know that this is going to be all over the web; in fact, I've found it in quite a number of spots. But I'm such a huge fan that I couldn't go without sending him my best wishes, even if he doesn't know me from Adam.
Good luck, Mr. Pratchett. I look forward to your next book.
