4.5 stars
First of all: as a public librarian the greatest horror I got from this book was sharing the MC's fear of bedbugs. You have no idea how much I related to that. Thankfully I don't have severe anxiety but boy was I familiar with some of Mari's habits!
Oooh, so many things I loved about this book:
-great, well-rounded characters (although I guess the 'is she possessed or is she just a little shit' stepsister trope was a little overplayed, but certainly made you frustrated!)
-Fantastic environment building
-Excellently-written horror: both supernatural and haunted house horror as well as trapped in your own anxiety and downward spiraling mental health horror
- The ending

Spoiler

But I'm in the minority when I say I enjoy abrupt, leave-you-hanging, lady-or-the-tiger endings, especially in horror.

I recently read The Taking of Jake Livingston which was teen horror that had similar themes and controversial topics, but where that book tried to cram too many issues into one book and didn't pay attention to its character development, this book took the time to develop, research, and really integrate these themes into the story.

I really appreciate the author's message about unfair imprisonments, legalization of marijuana, corrupt police, city health and safety departments being run from the pockets of investors and the rich and being under their control and not looking out for the good of the town/city, as well as the gentrification of old neighborhoods.
