One day when Percy comes home he finds a strange man in the kitchen talking to his mom. Little does he know that that will change his life forever. Set after TLO and during HBP

Percy gets a letter from Hogwarts asking him to attend the school for sixth year after his holidays.What happens when the two worlds crash? Takes place after the Giant War and Wizard war.

I have been betrayed; thrown away like yesterday's news. My brother has done nothing yet my friends fawn over him like he has saved Olympus. Even Annabeth has betrayed me. Having no friends, I ran away...and I became the second most powerful person in the universe. I am the Commander of Chaos. I am Percy Jackson.

Chaos, once though gone forever, has returned. He has demanded one child from every major god take part in a games - or trials - to test and see if they are as strong as the gods praise. Of course Percy is chosen to participate. When has something gone wrong and NOT involved him in some way. After his break up with Annabeth and the arrival of his vile half-brother, perhaps a challenge will be a welcome change? That's what Percy though, at least. Now it seems Chaos isn't all he appears to be, and once again - as tiring as it sounds - the world is in immediate danger of complete and utter destruction and Percy is the *only* person able to save it. Why some one *else* can't do it, he doesn't know! But he's far too entangled in the Chaos Trials to back out now... *characters belong to Rick Riordan*
