Hey! So this is just a story detailing if I were to create an OC for the MCU to write myself into it. Multiple relationships developed (familial with Tony Stark, Natasha Romanoff, & Clint Barton) and romantic (possibly Steve Rogers & Loki Laufeyson) I hope you enjoy! There's a song for each chapter. It's the Soundtrack I've curated. Here's a link to the playlist so far: https://music.apple.com/us/playlist/starling-soundtrack/pl.u-XkD035LsDKLPJbv *The character of Madelyn was created and is owned by me. I do not own any of the characters in the story except for Madelyn (often referred to as Mads or Maddy). All other characters belong to Disney, Marvel Entertainment, and Marvel Studios. I am not trying to claim ownership over these characters. If there is a dispute, please contact me, and I will gladly remove it. This is strictly a fan generated story.*

James Barnes was sixteen years old when his baby sister came into the world, pink and wrinkly and screaming her little head off. And James? James was unimpressed. She was tiny-too tiny. Her hands were no bigger than his thumb, her head barely covered in a fuzz of dark hair. She cried constantly, made Ma exhausted, and stole all the attention in the apartment. And worse? She was completely useless. Couldn't walk, couldn't talk, couldn't even hold her own head up or go get groceries. He had brothers. Brothers he could roughhouse with and throw punches at. This? This little thing wasn't a sibling-she was a baby. And yet, despite all his grumbling, he still found himself staring at her when nobody was looking.
