Before The World Took You

Y/N Stark and Bucky Barnes can't stand each other.
She's reckless, stubborn, and Tony Stark's daughter. He's brooding, infuriating, and the last person she'd ever choose to trust.
They were never supposed to fall for each other.
But somewhere between the arguments, the missions, and the hatred, something changes.
And when the past comes back to haunt them, they'll discover that some lines are easier to cross than others, and some secrets are impossible to outrun.
