The Distance Between Us

Percy Jackson, or rather, Percy Potter, hadn't seen his twin brother, Harry, since they were very, very little. You see, Lily Potter got extremely drunk one night, and, believing he was James, had a one night stand with Poseidon. She made the executive decision never to tell him, and so James never knew. On October 31st, the Potter family was attacked by Voldemort. That night, Lily Potter and both her sons survived, but before Lily regained consciousness, Dumbledore came. Lily and Percy were taken for dead. When they awoke, Harry was gone, Lily assumed the worst, and in a haze, she ran to the United States, hoping to start anew, and never think of that life again. But happens when Dumbledore asks Chiron for someone who can come to Hogwarts and protect it from invading monsters, and Chiron has just the demigod for the job. Percy is launched into the Wizarding world and a life he never had.

This book takes place during Half Blood Prince and after Blood of Olympus (just pretend Percy's still 16) Also, I do not own literally any part of this story, and am not seeking to gain money from it as if it was my own.
