(takes place in The Dark Prophecy) I got bored of all of the other nonaccurate Demigods go to Hogwarts and the only good one I found was updated 2 years ago so I figured I'd write my own

Harry stared at me. "You're just like him. Looks like you do take after your uncle," He sneered at me with an undertone of sadness," He killed my parents and tried to kill me, too. Is that what you wanted to hear? When I was eleven, eleven, He came back as one of my professors. He tried to make himself come back. But I beat him. Then," He pointed at Ron,"His little sister was possessed by the man who ruined my life. He almost got back, but we destroyed the diary and saved the muggle-borns. Then, I find out t hat my godfather was an evil mass murderer but he was actually innocent. Then, Ron's rat turned out to be Peter Pettigrew, who was Volde-" "Harry, no! You can't say his name!" Hermione burst in. She looked afraid. "We'll have to face the death eaters and we're not ready for that." "'Death Eaters'." I said in disbelief. Trying not to laugh, "Who would want to eat Thanatos?" ************* This takes place after Blood of Olympus, before The Hidden Oracle, and during Deathly Hallows. It is mostly in Harry's and Percy's point of view but a few others are thrown in. I worked really hard on this and I really hope you guys enjoy. The first couple of chapters are about 500 or so words but they get longer, I promise. If there are any spelling mistakes or grammar mistakes, feel free to comment them down below. It is an alternate ending to Deathly Hallows. Please don't kill me when you read the bonus chapter/ epilogue. In your demigodishness and all that, stay potterheads. Love you guys! Thanks for reading!
