WHOA! A black girl-centered horror? I'M INVESTED!!

Well I definitely am guilty of buying a book based on the cover and this GORGEOUS cover has me by the neck. Any book with a beautiful black girl has me interested, but that paired with it being a horror is what makes me interested.
The title also makes me interested, specifically the "subtitle" that says "and the best is me" cuz WHAT DOES THAT EVEN MEAN?!
