Well. That was the most upsetting crime anthology I've read this year. Read in a while, in fact. (This isn't a bad thing, just a heads-up.) Favourite stories were "Immaculate" by Marlon James, "Roll It" by Leone Ross, and "Sunrise" by Chris Abani.
Two of the stories (out of eleven) struck me as more slice-of-life than crime or mystery stories. Out of the remaining nine, two came across as merely solid--one straightforward, one that made me smile. A couple struck me as strange; the characters were well-drawn and behaving consistently with themselves, but I wasn't sure I could buy into how they interacted with each other.
The other five ranged from good but leaving me feeling like I needed to reread it on a day when I wasn't feeling slightly under the weather to leaving me sitting there thinking "I just read that? People do
that-- oh, god, they do. Ohgod."
I'm breaking it down like this because... honestly, having read the book, I am currently feeling very safe, and suburban, and a bit ignorant.
Well worth the read, not (personally) traumatizing, but worth making a small extra effort to note this is not a feelgood book.
 Which is not to say they are uninteresting. One of the two (namely "54-46 (That's My Number)") struck me as more of a mystery than a crime story; the other was "Immaculate", which, er, did not.
