The Chaos Chronicles

The Chaos Chronicles are the group of books that center around Zachery Aurelius, Dustin Magnus, and Rafik Sethos. Each person is a demigod son of a god from different religions. Zach is from Greek Mythology, Dustin is from Norse Mytholgy, and Rafik is from Egyptian Mytholgy. They all take place in the same Universe, which is the same as the Percy Jackson and the Olympians.

Prologue
The series takes place a couple years after the Last Olympian, as if The Lost Hero never happens.
