The Siblings Three (A Percy Jackson Advengers mix )

Hi my name is Ember and I am a daughter of Loki and my sister is Natasha Romanoff. When I turned three they put me in the red room with my big sister who was already 18 teen. We played and fought and trained together and all the people in the red room would say we were insepritible. Then the worst week of my life came when my demigod powers got out of control and the people in the red room separated us because of it which just made things worse and I was 5. Two years later Percy Jackson and Natasha meet and Natasha is a new agent at S.H.I.E.L.D. Percy saves her life by almost drowning a bunch of bad guys who shot her. He nurses her back to health and to repay him she teaches him everything she knows.
