The Giant war is over and Percy Jackson is spent. Finally there's a chance he can be with Annabeth for a while and he eagerly awaits the summer they have planned together. But when Hecate shows up and sends Percy on a new quest, it could be the by far stupidest thing he has ever done. He must be the new teacher at Hogwarts. Harry Potter has been attacked by the Ministry and Dementors. If that wasn't enough he now has a new teacher. But he is like, a 17 year-old kid. Who looks a lot like him. It's Harry's 5th year and he is now a nutter to the wizarding world. So when he sees the kid show up at Number 12 Grimmauld Place, he starts thinking he might actually be mental. The new kid turns out to be a teacher. The teacher of DADA. But Umbridge is still there- as the High Inquisitor. It seems she watches the new teacher-Professor Jackson- a lot more than the others. Something is off about him. And the Golden Trio always tries to find out what.

When Percy is summoned home from camp to see some weird people on his couch, let's just say he's confused. When he finds out that he has another evil relation, he's not happy. Well, off to Hogwarts. Harry is astounded. Voldemort- the lowlife scum of the wizarding world- has a grandson. Now Dumbledore wants him, Hermoine, and Ron to get him, and become friends. Harry must be crazy because he agrees to go.

What about Annabeth? How will Hogwarts deal with the awesomeness of Percy Jackson?

People who are born with two souls in their body are rare. But since when did Harry and Percy obey the rules? Follow them as they try to survive after their brother was mistaken for being the Boy-Who-Lived. AU. Wrong BWL

Chiron decides to send 14 of our favorite demigods to Hogwarts on an extremely important mission, because: Camp Half-Blood is a mess. The power of prophecy is unavailable. The magical border is down. Camp is constantly being attacked, and demigods are dying left and right. Once again, the gods don't seem to care. New dangers are arising, and the camp seems doomed. Hogwarts is doing quite good. Completely repaired from the aftermath of the battle, the school is thriving. The wizarding world has something the demigods don't. Will they save them, or destroy them? And will the demigods be able to survive a whole school year at Hogwarts, pretending to be normal?

[Completed] This takes place after the Deathly Hallows and after the Giant War. Nobody important dies, thankfully, nobody at Hogwarts is a demigod or demigoddess that knows that they are.
