I had a fucking blast with this one in the sense that I was stressed out the whole time. And of course I read it in one single solitary sitting. 

I feel like the atmosphere was properly scary but what was more I love horror where I don’t know what’s going on. I don’t know where the monster is, what it is, how it came to be. I don’t know for sure who’s still alive or who’s dead. Being stuck with one single perspective character meant that I didn’t know the rules and I was figuring things out alongside her - and that is really an excellent way to raise tension. Horror authors seem to forget that. I can even accept the ending - it’s not what I wanted but I’d rather be left with questions than given a tedious happily ever after. It’s horror, for fuck’s sake. 

I think my only issue is that there’s two competing storylines during the third act and frankly one of them is just not that interesting to me. I lost patience with the flashbacks and maybe that says something about me as a person but I just don’t care.
