It only took me 5 months to get to it (and through it) after Ed recommended that I read The Curious Incident of the Dog in the Night-Time. (I had a couple books higher in the queue, and I read terribly slowly these days.) It's really a great book and really a great relief to me that, all-joking aside, I definitely have very little in common with the Autistic. ;)
Seriously, though, read the book. More diligent readers than myself can easily plow through it in a day or so.
