At seventeen, you’re the youngest member of the Avengers — skilled, stubborn, and hiding a dangerous secret. Everyone believes you’re the younger sister of James Buchanan Barnes, and nobody questions it. Nobody except Steve Rogers. Because Steve knows the truth: you’re not Bucky’s sister — you’re his daughter. Hidden for years after Bucky’s capture by HYDRA, your existence was kept secret to protect you from the enemies tied to the Winter Soldier’s past. Now, living and training with the Avengers, you’re trying to balance missions, teenage life, and a father who’s still learning how to be one. But secrets never stay buried for long, and when people begin hunting for the “Winter Soldier’s daughter,” the lie holding your life together starts to crack.
