Percy Jackson goes to Hogwarts

Bear with me this is my first book and I'm really excited
so really don't expect good or correct grammar that my English teacher tries to grill into my head. ( ;

This takes place after HOO and deathly hallows
Ships will be
Percabeth (seaweedbrain perfect ship name fight me)
Frazel
Jiper
Caleo
Solangeloooooooo!!!
Hinny
And sadly Ron and Hermione will not be a couple
Snape, Sirius, Remus, Tonks, Dobby, and Hedwig are alive as well as Fred because I said so

After the war with Gaia the demigods were once again called to a prophecy they have to travel to Hogwarts to keep an eye on one Harry Potter they stay with Harry in grimmauld place and they soon find that an evil more so ancient that Kronos is arising as well as an old evil that the wizards fear have teamed up to take both the wizards and demigods down (lol this is going to sound soo cringey) join the wizards and demigods through trials fluff and yeah honestly it's a pretty good book.

Harry Ron and Hermione are suspicious and bratty towards them and they don't trust the demigods perhaps a few OC's created by readers and their will be no I repeat NO demiwizards.
