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.
When Lily has a favourite cousin who she considers to be the best sister she has who accepts her for being a witch more than Petunia and also be her maid of honour at her wedding who gets along with her husband and his two other friends after threatening him pain if he broke the lily heart.
Even when her son was born her cousin joked that they were twins looking alike when she was there at the birth before heading back to the USA to fix some god problems making her no contact for a few years
Only to learn when she came to London that Lily and James died and her son is with Petunia and her walrus husband being abused. Percy Jackson, the hero of Olympus, bursts into anger and rescues her 4-year-old nephew immediately defeating the real villain of the story and finding truth of her birth and her immortal lover.
