And wow oh wow, is it good.
I went into it expecting a straight-up horror story, and it very certainly delivers on the scary front, but it's so much more than that. It deals with power and race and class and it deals with how we often times treat—or flat-out dismiss—other people as less-than-human, as not-quite people. It doesn't just deal with haves and have-nots, it deals with how we—whether consciously or not—think of some other people as LESSER.
It's got a great, flawed protagonist; a fantastic, diverse-in-many-ways cast of characters; the various characters change and grow; it references other related books and movies in ways that are smart and sometimes surprising; it's hugely emotionally engrossing and satisfying; it deals very much with The System, and posits the idea that the system as-is isn't broken—but that it was specifically built for a certain set of people, and so all of the calls to Fix The System in order to better serve populations that AREN'T that certain set of of people are pretty much doomed from the get-go; it's thoughtful and funny and sad and occasionally will make you feel like you've been socked in the gut and at its core is absolute heart, empathy, love, and hope for humanity.
I loved it, I loved it, I loved it.
So. Make sure it's on your radar.
