Son of Chaos

Percy Jackson, betrayed son of Poseidon, now son of Chaos.
Percy Jackson was the 'Hero Of Olympus' that is until his half-brother came to camp. When HE came everything came crashing down for Percy.
What happens when Chaos tells Percy/Alpha that he and his team Fallen Angels have to go back to Earth to save the gods and demi-gods at Camp Half-Blood?
How will Alpha react to having to go back to Earth?
Who are the Fallen Angels? How will they react about going back to Earth?
Is Alpha dating someone? Who is he dating if he is?
Will Alpha and the Fallen Angels go back to Earth? How will they act when they go to Earth?
What happened to Percy that made everyone betray him for his brother?

I don't own Percy Jackson and all the other characters. They belong to Rick Riordan. Although I do wish I did own them but I don't.
