Vampires in forbidden love affairs, vampires getting married, vampires on honeymoons, vampires having babies. You can read it all in the fourth installment of Stephenie Meyer’s best-selling “Twilight” series, “Breaking Dawn,” which has spawned hordes of fans and a movie franchise.

But according to a little-known author named Jordan Scott, you may have read it all before. Scott, a California college student, claims Meyer’s vampire romance scenes were lifted from her 2006 novel, “The Nocturne.”
