Help from someone new: a KOTLC+PJO+HP Crossover

This is a Sokeefe + Percabeth fanfic, I ship all of the couples in HOO (Jason is alive) and I also ship Tiana as my other firm KOTLC ship. The rest I will sorta figure out over the course of the story based on the characters. BTW Leo did die but he's back and they're still mad at him.

For the actual plot: the gods have discovered the elves, but they aren't sure who to trust - the only campers made aware of their existence are Percy, Annabeth and Grover, they are doing one of Percy's quests for college rec letters (read Chalice of the Gods if you don't understand this). They are sent to investigate Amy's house, because the gods think of it as a rendezvous point for the elves. Facts are revealed about Sophie's parentage and a bunch of them go back in time to train at Hogwarts. Not going to spoil any more, you need to read it if you want to know what happens next!

Don't worry, this story is very appropriate and there will be no explicit stuff/smut!
