Book 2 of my Soul series! Check out Soul before you continue please!! Also sorry about the cover. I tried to make it fit but it just wont. If you wanna see it just go to my DA page, the link should be on my profile.

In the Undertale universe, a different human child falls down into the underground. Even though she is very young she will have to find her way home or stay there forever. ----- Big thanks to my friend from school who helped me out a bit.

After Frisk goes missing, Caitlin, Frisk's twin sister goes looking for her in the the last place she saw her. MT Ebott, the mountain of dark legends, she finds a necklace that belonged to Frisk on the ground. Just like Frisk, Caitlin tripped and fell into the Underground. Caitlin finds things she never knew existed.

**This is my first time in making story. So I didn't know what to put in the description.** This story is all about Asriel and Chara's backstory. I just love this game so much, so I decided to make a fanfiction. P/s: sorry if there's grammar errors in this story. My English isn't 100% accurate as it isn't my first language. I don't own any character in this story. Characters are belongs to perspective owner. #UndertaleByTobyFox I don't own any of this fanart in this story too. Every fanart are belongs to perspective owner. I'm just making a fanfiction. That's all. I hope you like my story! Sorry if the story is boring. I will do my best to make it interesting. :) <3
