Title: Level Up
Author: findthesea
Rating: Teen & Up
Pairing: Clint Barton/Natasha Romanov
Summary: This is what Clint Barton and Natasha Romanov remember about Budapest: Love is for children, love is a debt.
Author notes: Post Avengers. It takes more than one person to fight monsters and unmakings.
Warnings: Graphic Depictions of Violence, Psychological Trauma - nothing exceptionally heavy, but it comes with the territory of the subject matter.
