Invisible (Avengers/Captain America Fanfic)

All Sage Caruso ever wanted to be was invisible. Invisible to the people of New York, the world, and most certainly Shield. But when they enact the Avengers Initiative, they want to keep an eye on her more than ever. With a dark and unclear past, Sage enters the world of heroes for the first time. It's nothing like she expected. She certainly didn't see a young, strapping soldier from WWII coming. Will her secret ruin everything? Read this interesting take on The Avengers to find out...
