Percy Jackson x Harry Potter crossover

Percy Jackson has lost everything. The giant war took everything from him. The rest of the Seven and Nico were dead. He leaves camp knowing he wouldn't be able to stay any longer with all the memories of everything he'd lost, only to find his Mom and Paul dead. Gaea had gotten ahold of them and killed them before the battle at Camp Half-Blood. Now, the police are telling him he has to live with his aunt in England.

--------------------------

Harry Potter was already worried about what would happen this year now that Voldemort is back. Now, he is even more worried and confused with the sudden appearance of Percy Jackson - his cousin apparently. Where did he come from? He didn't know his mum had another sister. Why does Aunt Petunia like him so much? Something doesn't add up. Why does he seem to have a constant aura of sadness around him? Why does he have a broken look in his eyes? Why does he have so many scars? And what's the tattoo on his arm? Something fishy is going on and Harry intends to find out what.

--------------------------

Takes place after the giant war and during Harry's fifth year at Hogwarts.
