I have to admit I chuckled when I saw 'a literary vampire novel' come up as the official subtitle of this work, specifically because I felt what really made it an up-and-down read for me was its attempt to balance so much between being literary and horror, and I too often felt like the author wanted to write a literary novel, but 'make it vampire!', whereas I think I would have been far more satisfied by either a literary novel OR a horror novel, despite the fact that I often like mixed-genre work.
I did appreciate some of the character-study aspects here. The way the author incorporated issues of mental health and essentially made vampirism an eating disorder for the protagonist worked really well. The problem was that it felt like the novel was always either in literary mode or horror moved, and for a short novel, it opened up too many threads and then attempted to resolve them far too neatly, so that the ending was incredibly unsatisfying and underwhelming, as far as I was concerned.
I guess I can see why there was some hype around this book, but I don't see myself picking up something else by the author or recommending this one.
