Widow's Child (Fem Percy Jackson and Avengers Crossover)

After an unfortunate turn of events, young Persephone ends up with a very scary woman taking care of her.
She grows up with the woman (Later named Natahsa Romanoff) for years, until one of Nat's missions goes wrong.

Fem Percy Jackson and Avengers crossover. Will include most of Avengers Movie (but with some changes. Nat will be watching the tessaract project instead of Clint)
I own nothing.
