I'm actually right in the middle - I thought her humor was sometimes a bit forced, and her relationship with her dh is certainly not great but it didn't make me hate the book. I was, however, more than a little uncomfortable with some of the detail Decker gives about her sons' issues - especially her older son. Does she think her son's classmates won't hear about this book? How is he going to feel as an adult when people read about his grade-school aged obsession with checking his own butt for poop?
Still, it is an uncensored look at life with autism, and that is valuable when there's so much "inspiration porn"ish stuff out there.
In actuality, this is a very sweet story about a 17 y.o. suffering from OCD. I think the first sentence probably puts some readers off (on goodreads, anyway), but if it makes more teenaged boys read it, I'm all for it. Karo does an excellent job channeling a teen boy (maybe because he isn't too far from it himself?) and the social agonies of high school. And then there's the problems of seeing a psychiatrist, trying cognitive behavioral therapy, and medication.
