So Dorothy dies in Kansas; killed by a tornado. How does she come to Oz then? Wasn't the tornado supposed to carry her there? Well that part of the story is something I changed. Growing up I always thought that she had died, and that Oz was Heaven. Weird I know. I guess I never paid attention.
So now, all grown up, I decided to add this twist to the story we know. I think it helps place the story into the young adult section of the book store. I know, when I say "Young adult" people roll their eyes, but you may do well to recall the stuff you may have been reading at 10-14. I know I myself was reading Christopher Pike, RL Stine (Fear Street, not Goosebumps), and the Dragonlance Series. All of which have some pretty adult situations in them, without getting too explicit.
I don't think I want to go as far as Maguire did, and get really into the adult stuff (like making the Wizard a rapist). But who knows, the story evolves from one day to the next.
Back to Dorothy. She is buried by her Aunt and Uncle. A long time passes. Like a REALLY long time, and Earth isn't called Earth anymore. Four Witches come to a point, just by coincidence it's where Dorothy is buried, and they name the land around them Oz. And underneath them, Dorothy starts to come back to life.
