According to the International Association of Media Tie-Writers (IAMTW) web site, the Scribe Awards are for the 'overlooked' writers of media tie-in fiction. The writers write licensed works (i.e., not fan fic):

Our books are original tie-in novels, comic books and short stories based on existing characters from movie, TV series, books, games, and cartoons... or they are novelizations (books based on screenplays for movies and TV shows).

The IAMTW sponsors the Scribe Awards for media tie-in writiers. Their nominees for the Scribe Awards are on the IAMTW/Scribe web site. At the time of posting of this article, IAMTW had not posted the winners, but several other web sites gleaned the information from press releases. SF Awards Watch has posted all the winners. They report that the best speculative fiction original work is: Star Trek Terok Nor: Day of the Vipers by James Swallow.
