I don't think it really is a vampire romance, though I got my copy at the Romance Writers of America conference. I mean, it has some, but it treats them completely differently from other vampire romances. The book is really about the first-person narrator, Milagro De Los Santos, her voice and her life; the vampires are secondary. Also, her voice is strongly Latina, which is a nice change.
I'm not even done reading it yet and I already think everyone else should read this book and tell me what you think.
