So I‘m re-reading the entire Riordanverse (bc it’s been years) and I thought I’d make this to structure it more easily. Use it for help if you want!
Side note:
Chronological/timeline order. Companion books and Daughter of the Deep added just for fun (bonus prompts).

I’ve made a new challenge with the exact same contents, but the feature of it being set books, not prompts. Feel free to migrate or stay here.
