Another 2.5 that I'll rate as 3 stars. I read this since I was interested in how the book was compared to the movie. My only other Tremblay book was Head Full of Ghosts which I read a long while ago, but remember kind of liking how you couldn't tell if what was happening was actually supernatural or just humans being awful and idiotic. You'll get the same in this book. Which I enjoyed that aspect. And don't get me wrong, I usually enjoy those nebulous, open-ended, Lady-or-the-Tiger endings, but this one.... not as much.
