A new enemy (Percy Jackson Fanfiction)

GO READ MY OTHER DEMIGOD BOOK!!! I can't stress that enough. you will be horribly confused if you don't.

WARNING: there are some triggers in this story that include Cutting, abuse and Tourcher. Also mild swearing. If you don't like, don't read. DARK THEMES! I also have no medical knowledge at all so please don't follow or believe any of the medical things I put in here.

Less important warning: I'm still French and a terrible writer. corrections from people who are English is appreciated.

Disclaimer: I'm only saying it once so listen up. I own almost nothing. most characters and settings belong to the amazing Rick Riordan. I also don't own ANY photos (including cover) so they belong to whoever took the picture.
