Callie Jackson and The Avengers

What if Percy had a twin sister that was raised on Asgard and manages to catch the eye of a certain SHIELD director? Meet Callie Jackson, daughter of Poseidon, and adopted sister of Thor and Loki. Callie didn't want to join SHIELD at first, but then she met an extremely charming man-out-of-time. Pairing is Captain America x OC. T cause I'm paranoid. Temporary Hiatus.
