If you’re looking for something to read online, there is always fan fiction.
For example, FanFiction has 50,000 stories based on the Star Wars movies and 800,000 inspired by the Harry Potter books. The TV series Father Ted, on the other hand, has produced a measly 15 stories.
On a similar site, Archive of Our Own, there are 50,000 works about the band One Direction. For instance, Fading is 202,393 words, about twice the length of an average novel, and has been translated into Spanish. It starts like this:
Louis almost snaps when there is a light tap on the door of the studio. His knuckles go white on the edge of the cutting table but he forces himself to take a deep breath and put on a smile before he turns around. He isn’t the type to take his frustrations out on others, he prefers to take them out on himself. When he turns he finds Liam poking his head just past the door frame, hesitant to come in and disturb Louis.
Only 202,309 words to go!
FanFiction has a rating system for its stories: basically, K = Kids, T = Teens, M = Mature. The site “does not accept explicit content”. Archive of Our Own’s rating system is G = General, T = Teen, M = Mature, E = Explicit. A lot of fan fiction describes romantic/sexual relationships and this is normally indicated at the beginning of the story, along with any other content warnings.
