"Let us violate cakes together"
In "Redshirts" by John Scalzi
I applied for a job to be a licensed fiction writer of sorts last year - it was working on flavour text and copy for the Star Trek Franchise. The interview was heavily focused on my ability to write within the constraints of their authorial voice and existing publications - as stringent as working for any publication with a house style. That's not quite, I admit, the same thing as writing tie-in novels - but the attitude of IP holders to how licensed authors should write I experienced seems very much to be more like writing for a journal or newspaper than writing fiction - the job I applied for would very much have been technical or copy-writing about subjects that were fictional. Definitely a "specific skillset" as this Scalzi’s novel shows once again - but in retrospect I'm quite glad I didn't get the job.
