A blogger has put together a great list of ways famous authors in our world would’ve written Twilight had they had a similiar idea as Stephenie Meyer.
What came out of it is a fun read putting Edward and Bella in hilarious situations!
A sample of the ideas:
The novel takes place over the course of twenty four hours, during which Bella is painting a portrait of Edward and reflecting on how her femininity circumscribes her role within 20th century society.
In the opening scene, Edward dashes Bella’s head against a rock and rapes her corpse. Then he and Jacob take off on an unexplained rampage through the West.
Basically the same as the original, except that Bella is socially apt and incredibly witty. Her distrust of Edward is initially bourne out of a tragic misunderstanding of his character, but after a fling with Jacob during which he sexually assaults her (amusing to no one in this version) she and Edward live happily ever after.
