This was a very strange book, but compelling in its way. It is more horror (specifically body horror) than romance, but there were romantic elements too. The premise was never satisfactorily explained and the ending didn't entirely make sense. But the writer is talented at creating an atmosphere of helplessness and fear interspersed with moments of bravery and affection. Some found it to be quite erotic as well (I was way more "idk" than "yum" about the sex myself). There is a lot of sex, but most of it is under drugged, dub con conditions. Again, weird but compelling in its way.
So, I guess recommended for people who want something with body horror and sex, offbeat with scary and suspenseful moments, but a reasonably happy ending?
