THIS IS A SEQUEL BOOK!!! IF YOU HAVE NOT READ THE FIRST BOOK YET THEN GO FIND IT ON MY PROFILE!!! Anyway, now for the summary: After death, you hadn't expected much to happen. You fell immediately into a place like the void. You just wanted to reconcile for what you'd caused, but your heart had a wish of its own. You wished to turn back the clock and set things right. You wanted to make everyone forget your existence and make them happy again, even if it left you alone. Well, you're one of the lucky ones. You're wish came true and you reset time. But not everything went to plan.

This is a Slowburn so hate me all you want, I dont care. If you dont like it then dont read it. Basics: y/n-your name l/n-last name e/c-eye color f/c-favorite color h/c-hair color s/c-skin color Setting: Monsters were released from the underground and onto the surface. The Humans were use to living with them but not until another war broke out and yet some humans despised them. Humans hunted down monsters as the monsters go into hiding, trying to avoid from being killed. You were walking home from the store but stop midway when you hear sirens and cop cars going down the street. You follow and come across a skeleton who you saved from police forces.
