Chaos's 10

After the Giant War, Percy Jackson expected everything to be normal. He had his girlfriend, he was back at camp, there was no way Gaea was coming back any time soon. But after he gets kiddnaped in the middle of the night by Chaos, and was brought together with nine others, he realizes there's a whole lot more than Greeks and Romans.

There's the Egyptian gods, the Norse gods, and even Angels and Demons running around on earth everyday.

An upcoming evil threatens very creation, and the ten are the only ones who can stop it; the best all of mythology has to offer.

With Chaos, they train and become the ultimate team. After 500 years, they return to defend the earth.

With all of the worst gods and goddesses coming back from oblivion, the only thing even Chaos doesn't know is "How are they returning?"
