Mexican Gothic, Silvia Moreno-Garcia. Set in 1950s Mexico, a pretty Mexican wealthy socialite living a party life in Mexico City gets a disturbing letter from her cousin, who has married into a once prominent but faltering (and slightly off) family in the countryside, so she ventures out to their dilapidated mansion to help her cousin, although help her "with what" she isn't sure. Has all the "Gothic" elements of the title; countryside/creepy manor, dashing strangers, weird happenings, isolated location, misty cemeteries, etc. Very well written story, it starts out quick and keeps up the pace as our heroine tries to figure out what is going on. Supernatural occurrences? Scientific explanation? Or are we just hearing from an unreliable narrator? Good novel and satisfactory finish (won a bunch of awards). I'll probably return to this author at some point.
It was slightly odd, though; I reviewed What Moves the Dead (Ursula Vernon) last year, which was a retelling of Poe's Fall of the House of Usher in which Vernon attempts to layer in more concrete explanations for the paranormal activity that Poe leaves largely unexplained. The odd party is that Vernon and Moreno-Garcia land on virtually identical causes of the strange happenings. Seems at first blatant plagiarism (Vernon's book came out after Mexican Gothic), but as it turns out it was a coincidence, and Vernon was half-way done with What Moves when she learned about MG and almost shelved her project because of the similarities, but instead finished and published and chose to address the similarities head-on and explain the coincidence. I tend to believe her.
