Where The Sea Meets The Sky (a Heroes of Olympus Fanfiction)

After the defeat of Gaea, Percy Jackson is attending college in New Rome. Jason, meanwhile, is camp-hopping in order to accomplish his goal of constructing cabins for all the minor Greek and Roman gods, with Nico helping. As life seemingly continues to go on as normal, the calm is hiding a storm that might turn the world as the demigods know it upside down.
Revealing secrets going back to the fall of Gaea, and even farther to the defeat of Kronos, life hangs in the balance as the demigods threaten to be overwhelmed by a force as primordial, if not more so, than the Earth herself.
