Fanfiction or book?

Fan fiction is not able to be published for money.
So I'm writing actual books I can publish for money.

Makes sense. Although, there have been instances of fanfiction so well received that the author rewrote it into something original and got published that way, pointing to its popularity in the original format as an argument that the idea could sell in the market. So it could be a decent strategy and testing ground to get attention from an existing fanbase as a jumping-off point.

When I wrote my first fiction book during NaNoWriMo, it wasn’t exactly fanfic but every time I was stuck I would think “what would Antonia Forest do here?”

I kept rewriting afterwards it but it has not been published!

Fifty Shades of Grey was famously fanfiction with the names changed before publishing, but works have been published in which the names were not changed before publishing — springing to mind immediately, Wicked is fanfiction of The Wizard of Oz, and I've heard it argued successfully that Dante's Inferno is fanfiction (that is, derivative fiction based on the world and/or characters developed in a previous work by someone else) of the Christian Bible.

>10 GraceCollection: correction to that: Yes, 50 Shades was originally Twilight fanfiction and forced to change things. Wicked was NOT fanfiction, it has a contract with the estate of L. Frank Baum to work in his world and use his characters. Though technically didn't need the contract because The Wizard of Oz entered public domain in 1956.

>11 gilroy: I'm not sure a contract negates Wicked being fanfiction... it's derivative fiction based on the world and characters developed in a previous work by someone else. It may have been authorised by his estate, but it certainly is not an accepted sequel in the vein of Star Wars authorised works all being part of the same universe.
