Forbiden Fruit

Forbiden Fruit: the tempation of Edward Cullen (note the spelling errors in the title) is the Twilight fandom's answer to Legendary Badfic My Immortal. Rumour has it it was written by the same person, and it's definitely just as insane (and funny). This one stars a similarly "goffik" Mary Sue by the name of Atlantiana Rebekah Loren, otherwise known as Tiana or Tiaa.
