Rating: T (cuz we're paranoid)
Main Characters: Jace Anderson, Percy Jackson, Luke Castellan, Erebus (Gaea's brother), basically everyone from PJO + HoO
OC: Jace Anderson

Synopsis:
Gaea and Kronos are back, power hungry and wanting revenge on Olympus more than ever. They’re not the only ones back, too. The demigods of Camp Half-Blood feel an odd presence in the air after the new camper has been here for a while. Luke has somehow been brought back to the mortal world, and the demigods need to know how. And who is the mysterious new camper?

Disclaimer: Everything from PJO & HoO belongs to Rick Riordan.

A/N: There will probably be sequel(s).

Kronos429 and I will take turns posting.
