Listen, this book was not at all marketed correctly and I think that's why it's not more highly rated. It's not reeeaaaallly a horror book (despite being a Goodreads nominee for best Horror last year). It's more a supernatural western romance or a speculative historical romance, emphasis on the romance. As a romance reader, this was a hell yes five star read. But for the folks who don't read romance, they got pretty uppity about Nena and Nestor's relationship being the primary narrative driver here. Which I totally get! If I read one more "romance" that is actually women's fic, I might go throat punch a stranger. Anywayssss if you go into this expecting an epic second chance romance struggling to blossom in 1840s Mexico in the midst of a super scary vampire infestation and the Mexican-American war I think you're gonna have a good time. I inhaled this in less than 24 hours.
