What kind of genre is the book twilight?

*SPOILERS The fantasy elements are obviously the vampires but in the second book New Moon, the Quillette warewolves are also fantasy, along with the 'gifts' that the vampires possess. The romance elements are Edward and Bella; Jacob and Bella; Jacob and Nessie; Emily and Sam; Carsile and Esme; Rosalie and Emmette; Jasper and Alice; and so on. This answer is from the whole Sega and I apoligise if I ruined any bit of your Twilight experience. P.S. Sorry if my spellings are wrong, that's not my strong point=D
