Nothing is left alive but one human.
This Human was Y/N. But for some reason she does not only survive but also gets powers some of which include teleportation and travel throughout the multiverse.
She ends up on the dirty, cold and wet streets of
New York but in this multiverse the avengers exist.

What will happen? You will find out.
The first chapter is supposed to release the second week of July of 2023
