The seven plus Nico, Thalia and Calypso are going Hogwarts to protect the golden trio from the war that is coming. The combined forces from Gaea, Kronos and Voldemort are planning to attack Hogwarts and Camp Half-blood by the end of the year at Hogwarts. Read to find out what happens. A/N: I am horrible at descriptions I promise the story will be better and also I do not own PJO, HoO and HP the two amazing authors JK Rowling and Rick Riordan do. I only own the plot and any characters I make up *This takes place after the Deathly Hallows and BoO and Dumbledore, Fred, Tonks, Snape and Remus and anyone else that died in deathly hallows is gonna be alive ok*

JK Rowling and Rick Riordan own everything. Takes place in Harry's fourth year. Ginny takes Ron's place in the Trio. The Seven are having a peaceful summer. Leo found his way back with Calypso and everyone is happy. Gaea has been defeated and all threats are gone, so they thought. Chiron gets a call from an old college, Albus Dumbledore, saying that a very evil wizard is arising and he wants protection on his target...Harry Potter. Chiron chooses his best demigods. Unfortunately for the Seven, that means they have to uproot their lives and go to non other than Hogwarts. I know the age differences are crazy, but just go with it please.

Percy, Annabeth, Thalia, and Nico must take a trip to Hogwarts in order to keep the golden trio safe. Will they be able to rise to the occasion to help them defeat Voldemort at his rise, or will everything fall apart?

I know a lot of people have done this type of story but I wanted to give it a try. The seven plus Nico go to hogwarts with a little twist. I'm not really good with descriptions so please give this a try.
