The new Kindle Worlds platform will enable any author to publish stories based on these characters and then make them available for purchase through the Kindle Store. Amazon will then pay royalties both to the author of the fan fiction and the original rights holder. The standard author’s royalty rate — for fiction that is at least 10,000 words in length — will be just over a third (35 percent) of net revenue.
