Permission to use Rick Riordan characters

Question

I am already working on a novel with Rick Riordans characters and was wondering if I could get permission to use them from his copy right holders before l proceed with book 2 that has THE KANES introduced. Hope you understand.

Answer 1

Took only typing Rick Riordan fanfiction into Google to find this:

Do you ever read fan fiction?

No, never. I am aware of fanfic, but I go out of my way to avoid it. For one thing, it's legally tricky ground. I can't actively endorse anyone else using my copyrighted material. I also don't want anyone claiming later on, "Hey, you got that idea from my fan fiction!"Aside from that, I have to admit I find fan fiction a little unsettling. It's like somebody getting into my closet and trying on my clothes. It's just weird seeing someone else try to write about my characters. Then again, I can't listen to the audio versions of my books. It drives me crazy hearing another voice beside my own narrating my stories. And, as I've explained many times, I also couldn't watch the Percy Jackson movie for much the same reason.

I love the series so much I'd like to continue writing the books myself. Can I have permission to use your characters and ideas?

I’m honored you like the series so much, and I get this question frequently, but my publisher would be pretty upset if I gave anyone else permission to write about Percy's world. If you’re writing stories just for your own amusement and not planning to publish or share them, that’s no big deal. But if you are hoping to write a book that would be published some day, you need to come up with your own characters, settings, and stories. Of course, Greek mythology itself is thousands of years old. Anyone can write about the gods and monsters. Perhaps you can come up with your own original spin on that material.

So it really doesn't seem likely you'd get that permission to write and officially publish your work. Hobby, noncommercial fanfiction seems to be tolerated though.

Answer 2

I don't know what you want from us then. Contact the copyright holders of Riordan's works and inquire with them. We cannot answer for them.
