What happens when Camp Half-Blood and Hogwarts meet? Percy Jackson is asked to teach at Hogwarts as the new DADA teacher, but will he last as a professor? Voldemort is getting ready to kill Harry, and the war is coming up. Will the demigods ally themselves with the wizards? Or will they let their differences split them?

This story takes after Heroes of Olympius and Deathly Hallows. The demigods: The seven, Nico di Angelo, Will Solace, Reyna Avila Ramirez-Arellano Thalia Grace, Calypso and Rachel Elizabeth Dare were sent to Hogwarts to study and make allies. But when they arrived, they were mistaken as Death Eaters by Harry Potter, Hermione Granger, Ronald Weasley and Ginny Weasley. What will happen in that school? Will they have a normal year as they wish or will they get into trouble again? I do not own any characters but J.K.Rowling and Rick Riordan does.

Harry Potter and co. are in they're fifth year at hogwarts. The PJO crew is teaching them and eventually helping them beat Voldemort. Percabeth, Jiper, Leo/Hermione, Nico/Ginny, Harry/Cho, Draco/Lavender, Neville/Luna, and Ron's a loser he can't get a girl. Did I mention that Harry hates the demigods?

The giant war is over. The Hogwarts battle is done. Many lives were lost. The boys thought their lives would be finally free of horror. But what they witness next is beyond what they have ever know. Join the two legions. Join Percy and Harry on there next adventure. Join Percy as he teachers at Hogwarts.

Percy is informed that he will have to teach at a magic school called Hogwarts. Just after a war. Harry is suspicious of his powerful new teacher and wants to find out what he's hiding. And why are Luna, Neville and Draco suddenly best buddies with each other and know the professor? I own nothing. STORY IS NOT MINE!!! ITS FROM FANFIC.NET @StarFlight13(although I will continue it)

Voldemort is alive, and growing stronger. The Ministry are ignoring Dumbledore's warnings and are making him out to be an old fool to discredit him. The Order of Phoenix are trying their best, but they aren't certain themselves. Harry Potter is losing his cool....and Albus Dumbledore is contacting Percy Jackson. Dumbledore needs Percy...knows that Harry is the one destined to defeat Voldemort, but desperately needs help. So he asks Chiron, and Percy Jackson is sent to Hogwarts to protect Harry.

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.
