Fanfiction that involves self - harm is a very serious and disturbing topic. It's not something that should be promoted or recommended. 'Percy Jackson' is a great series with positive themes like friendship and heroism, and we should focus on those aspects rather than such harmful fan - created content.
I don't recommend seeking out self - harm fanfiction related to 'Percy Jackson'. Such content can be triggering and not in line with the positive spirit of the original series. Instead, look for fanfiction that explores the adventures, character development, and relationships in a positive way.
