Ok, so this might sound weird, but I had this idea that Percy was adopted by the Dursleys. But that's not all! When he is adopted he's a year older than Harry. Harry is eleven and Percy is adopted during the school year. You know what this means? Harry's not aware that Percy exists, because Percy's not a wizard. Please read, I know it sounds weird, but maybe give it a chance?

Thalia and Reyna get sent to Hogwarts by Artemis, Chiron and Hecate as part of a widespread campaign by the demigods of Camp Half-Blood and Camp Jupiter to form alliances in case they were ever attacked again. This takes place one year after the events of HoO. In this AU, Reyna joins the Hunters shortly after the war with Gaea, leaving Camp Jupiter in the hands of Frank and Hazel. Note: With the exception of my OCs, all characters belong to JK Rowling and Rick Riordan. Also there will be TWs when required, but I will put one for swearing here, since people always react differently to swearing. Finally, I'm quite new to writing so please give some feedback and don't massacre me for mistakes :)
