[Set after Percy Jackson and The Olympians: The Last Olympian & in Harry Potter and The Order of Phoenix] Note: This is the rewritten version from @foreverdieyoung13 ;). It's three months after the Second Titan War. The demigods are still recovering after the event, but they're slowly becoming themselves again. Percy Jackson was hoping for a normal life. Well, as normal as a son of Poseidon can have. One war is enough for him, he didn't wanted to be involved with another. Rather unfortunately for him, the Fates and the world think the opposite. Percy was now thrust to a completely new world with Thalia and Nico. They have to go to the Wizard school for a year undercover. Great.

Set six months after the House of Hades, and in the Harry's fifth year at Hogwarts. Percy Jackson, Son of Poseidon, Hero of Olympus and more recently, Survivor of Tartarus, has been given a quest. Along with his two cousins Nico Di Angelo and Thalia Grace, he must go undercover at Hogwarts School of Witchcraft and Wizardry for a year. Their objective? Protect Harry Potter, Ron Weasley and Hermione Granger. Harry has had a rough summer, what with the dementor attack and the Dursleys. He thinks life back at Hogwarts will turn things around, only to realize that he is facing a year of ignorance and scorn. When the golden trio meet the children of the Big Three, will they become friends, or worst enemies? *Currently being rewritten under the same author. I'm leaving this one up for anyone that still wants to read it, but you can find a slightly different, hopefully better version on my page*

What if Percy, Annabeth and Thalia aren't just demigods. What if Percy's mum is a witch? What if Annabeth's Dad was a wizard? What if Thalia, though her mum is mortal, what if she is a witch? What happens when they go to Hogwarts and be friend the golden trio? Be prepared for a whole year of trouble, fun and secrets. I do not own Percy Jackson or the Heroes of Olympus. Rick Riordon does. I do not own Harry Potter. J.K. Rowling does
