The Seven have had peace. Apollo's became a mortal, but that was sort of cleared up after a year. After a war, but that's not completely unusual. The demigods met up after the war to catch up. When they talked, they realized weird things were happening. It wasn't sudden like, Chris-and-Clarisse-broke-up weird. It's more like Percy-hates-blue-food, Leo-refuses-to-use-fire, and Hazel-is-cussing weird. Not that any of that happened... Or did it? Everyone is determined to find out what's wrong. The demigods are asking who can they trust? The real question is, who could be doing this, and how? Disclaimer: I do not own the Percy Jackson and the Olympians or the Heroes of Olympus characters. Rick Riordan does that.
