Jim Henson website is holding an author quest (i.e. competition) to select an author to write a new novel in the Dark Crystals universe. Here’s a link to the Dark Crystal’s website announcement.
To submit, send a story of 7,500-10,000 words representing the story you wish to tell in the Dark Crystals universe. The prize money for selection is a $10,000 and an opportunity to publish the full novel.
I should also note that I learned about this first through another blog, aerogramme. They do periodic posts announcing competitions and such, as well as post useful author advice, and have been added to the blogs/vlogs resources on this site. Here’s a link to their article on the same topic.
