Hey Jep. I’ve worked in publishing, as an author, editor, marketer and publisher for over 30 years, and I can tell you there are no hard and fast rules, and if there are rules, there are always exceptions. I have limited experience with urban fantasy but as far as sci fi goes there are plenty of successful circa 50k (200 page) novels out there. My own publishing company is currently publishing a circa 36k debut sci fi novel. The story is the story. It is what it is. It ends where is ends. Impact is more important than duration. Good luck with your writing
