Not exactly mainstream fiction, or even mainstream scifi, but it’s based on an Xbox game published by MSGS.
The central character (not the protagonist) is described as having autism and several parts of the book are from her perspective. I thought it was interesting and a generally positive treatment of a character on the spectrum.
Not sure how Drew came to the character or whether she will put in an appearance in the Mass Effect sequel, but I sent him an email to ask.
It was a pretty good book, but in the interest of full disclosure, since Mass Effect is my all-time favorite single-player game, bar none, I would’ve read the book any way.
