Was it Stephenie Meyer or Rory Emerald who authored New Moon?

It was Stephenie Meyer, for sure. She wrote all 4 books in the Twilight Saga (Twilight, New Moon, Eclipse, and Breaking Dawn). Rory Emerald is a prankster... he's famous for making fake clified ads claiming to have found bizarre items like a 2- headed kitten. So yeah, he didn't write it. Maybe he claimed to find Edward Cullen, though. ^-^
