The Curious Incident of the Dog in the Night-Time by Mark Haddon
Curiously (ha ha! couldn't resist!), I read this book at the same time I was reading Louder Than Words. Curious because The Curious Incident of the Dog in the Night-Time is narrated by a 15-year-old autistic boy.
This is a really good book. (I know that's a lame description or review or whatever, but I have good music in my ears right now and I'm distracted. Thanks, Pandora!) There's a mystery, lots of insightful insight into a functional autistic mind, some humor, drama, family stuff. It's also a quick read. Jon read it, too, and liked it.
