After the war Percy is happy that the battle is over and Percy wants to marry Annabeth. Things go wrong in many ways for Percy and Percy is losing himself when he returns. Very few looked for him. There is one girl who can bring the old Percy back. She is long dead. Or is she? Gal Jackson is Percy's twin sister who fell off a cliff when they just found out about the demigod world. This whole time she has been trapped from seeing the night sky, the moon and stars, from seeing just a tiny cloud. The only comfort was that her trap was in the sea. Shall she escape and see Percy? Or will she escape only to never see her family again? <this is both a Percy betrayed story and a Percy's twin sister story. WARNING!: this contains the use of foul language and mature scenes such as gore and sexual themes. Also hints to Percimis and Oc X Luke(hint hint on the story) you've been warned!>
