I enjoyed reading this book, but I think it's been let down by its marketing. This book is, at least in part, marketed as horror (the library copy I read certainly has a horror label on its spine), and I think it's much more in the realm of "weird literary fiction" (which I don't mean as a criticism!). I found at around the 100 and 200 page marks I caught myself wondering when the horror was really going to kick in, and if the book hadn't been marketed as horror I would've just been enjoying my reading experience instead of comparing the book to what I thought it was going to be.
Overall, it's a weird book about a sad young woman with an eating disorder. There's a few passages that might be classified as body horror. I liked reading it! But I think the marketing is setting up some readers for disappointment. I will absolutely be looking out for other works by Margie Sarsfield, I thought she wrote the shit out of this book!
