Read on a recommendation and I really really don't understand the hype. Sure, the concept was cool and intriguing and there are some interesting ideas here and there, but not only is the execution flawed (pacing and characters are off) but the final twist makes no sense? Why would (view spoiler)[a school for the blind be windowless? Is that a thing in America? I know for a fact schools of that kind have windows over here. I mean... Why wouldn't they? What about the blind pupils with residual sight? Disabilities are on a spectrum, it's not all-or-nothing! What about seeing teachers, staff, parents? I mean clearly, there's light in there since Malorie can see... Why would the school rely exclusively on lamps rather than use natural light? I don't get it, I am baffled; if you needed a windowless building, why not try a mall? (hide spoiler)] In short: baffled. 
 Also, I was disappointed to realise that (view spoiler)[the blind survivors were not, as I first thought, blind people from before who were naturally immune to the creatures and would be best suited to adapt to a world where seeing is basically a death sentence, but abled (or seeing, at least) people who purposely mutilated themselves. So, OK. But then what about the people who were blind before? What happened to them? Especially considering te survivors live in a school for the blind! (hide spoiler)] 
 Also also, afterbirth is a thing. I'm not gonna say anymore about that particular ridiculousness. 
 Anyway, it had great potential but saying it fell short would be a giant understatement. It's bad. It's really just plain bad.
