Fandom you haven’t read but might one day
Firstly, just to clarify, the word ‘fandom’ in this case refers to fan-fiction, not the source material. I had a lot of difficulty with this question because if I have read/viewed/played the source material, chances are I’ve read at least one related fanfic.
After pondering the issue for a while, I finally settled upon the movie Love, Simon which is based on the novel Simon vs. the Homo Sapiens Agenda by Becky Albertalli. I have not read the book yet, but I absolutely loved the movie.
I have not checked my favourite fan-fiction sites for stories related to either the book or the movie. However, it is highly likely that I will do so after I get around to reading Albertalli’s novel.
