Thirteen year old Rosanna Woods' life turns upside down after she's adopted by Tony Stark's best friend. With a new name and a better life, she's determined to help her Dad and Uncle Tony be superheroes, but it's not always so easy. Her skills as a hacker and hand-to-hand fighter come in handy over the next few years as she gains a new family of Avengers along the way. Rosanna makes it her job to call the Avengers out on their stupid decisions and makes life so much better for the people of the MCU. She's ecstatic that her newfound family of reckless, dumb and immature superheroes is growing so quickly, but she makes it a point to be there for everyone. It's not easy, balancing work and all her extra Avenger-related activities, but she manages quite well. A.K.A the MCU AU you didn't know you wanted, where the team see past their differences and band together to form a tight-knit family that leaves no one behind. Just because there isn't a Thanos or a Civil War doesn't mean that the Avengers are gonna have easy lives... Cross-posted on Wattpad and Fanfiction.net
