Chapter 1 (Apollo)

This comes after Trials of Apollo, so major spoilers for Percy Jackson, Heroes of Olympus, and Trials of Apollo. Might be a few spoilers for Kane Chronicles or Magnus Chase, but I wouldn't worry about those (I'll give spoilers specifically for that chapter).

After the war with the Emperors, Apollo had been restored to his throne on Mount Olympus. One day, when the gods were arguing the fate of a certain demigod (cough cough Meg cough cough), Apollo lost it. He summoned Rhea and had her turn all of them into Mortals, just as he had been, to truly understand the mortals better. How will the gods respond and defeat a new threat that approaches? We shall find out.
