Horror novels that are based in Mexico or have a lot to do with Mexican culture.

My wife likes vampire books and ghost stories and stuff like that and she's been reading a few of them lately so I would like to find others for her. she is of Mexican descent so she enjoys one's that include a lot of Mexican culture and if it takes place in Mexico that's even better. she prefers them to be in English because that is the language that she grew up on but she is also bilingual. and one last thing if there are audio books of these books that would be absolutely perfect but I can try to find those on my own. thank you so much!
