Only Broken Inside

Skypper Paccioretti is no hero.
She's fighting to pay the rent, not to save lives. That is, until one day, out of sheer boredom, she ends up plotting to infiltrate a dangerous crime ring with a few friends. She tought she knew who she was. But life as funny way of proving you wrong.
She's not supposed to exist.
And the Avengers figured that out long before she did.
They'll watch her, search for the tiniest flaw, trying to prove she's not who she claims to be.
The truth is, she doesn't even know she's pretending. She truly believes she's just a broke, gifted kid that no one truly understand, not even herself.
Except for one person.
A certain ex-assassin with a metal arm. In a world full of chaos and lies, two broken souls end up finding other.
