Percy Jackson, The Wizard?
What if Percy Jackson had known all along about his heritage. No not the demigod stuff, no. He's a wizard, grandson of the villainous Voldemort. What happens as he grows up as a wizard kid, trying not to let others know who his grandfather is. Then finally, at age eleven he goes to Hogwarts. There he meets Harry and the gang. Of course his demigod friends make strange appearances throughout this, like Thalia, being a ghost? That's right my fiction loving friends, another shameless attempt to merge Harry Potter and Percy Jackson together.
