I read a short story in a horror/scifi anthology back in about 2005. Not sure when it was actually published. There was a love theme to the anthology.
A girl hung out by graveyards and ended up becoming a ghoul. When a ghoul would eat the living, they would take on the memories and personalities of the person they ate, for a very short time. It was mostly comic relief for the other ghouls.
But the girl who became a ghoul fell in love with another ghoul, and they ended up killing and eating a young couple who were in love so they could experience love.
Ringing any bells?
