Art is not mine!

This is my first ever written story and I apologize now for my grammar mistakes and if it doesn't make sense. English isn't my home language nor my second language.
I once read a book similar to this but I don't know the books name and the name of the author.
You can upload my story only with Credit.

Warning:
There might be some violence and blood.
Bad language and more.

Enjoy!
