This is just a little info you may find helpful when reading this story. I don't explain much about the kids, so here you go.
It's been seventeen years since Steve Rogers walked out of the Avengers Initiative. He had gotten into a fight with Tony and it was so bad that they broke up. Little did Steve know that Tony had been experimenting with trying to have their baby. Tony was pregnant when Steve left, not that Tony even knew at the time. Now their three sixteen-year-olds are on a search with their friends, the other Avengers' kids, to find their missing father.
Sophia is the youngest of the three siblings and she has taken the spot as the leader. She is leading the team of thirteen kids, ages five to sixteen, to find the man she'd only ever heard stories of as a child. The story is mostly all in Sophie's point of view.
