Big Sister Undyne

Underfell is a dark world with the major rule of kill or be killed. Even though children are suppose to be secluded from this rule, that doesn't stop monsters from hurting children.Undyne is a monster who lives in Waterfall. Under the care of Gerson. One day while out on a walk the fish monster stumbles across a baby. Though it wasn't any monster. It was a small little baby skeleton.(the cover is only temporary, until I'm able to make a cover for the story)

Fight or Mercy | Underfell x Abused! Reader

[2nd book] ((COMPLETED)) {Undertale AU - Underfell} [WARNING:ENDING AND PLOT IS VERY CRINGEY] "Long ago, two races ruled the earth, the Humans and the Monsters. One day, war broke between the two races. Many have fallen to serve their kind. Years later, the humans were victorious. With their magic, seven of their strongest wizards sealed all the monsters underground with a magical barrier. Only a human soul could pass. Mt. Ebott 201X, they say those daring enough to climb up the mountain.... never return. ""Leave them, Y/N! Run! "___________________________________________I'm a Undertale addict. I freaking love the story line and characters! One of my favorite AUs is Underfell so I'm finally making an X reader. Also, if there are wrong spelling or grammar, please tell me. I'm using GoKeyboard. Enjoy my Crappy 2nd book!

A Step Outside the Door

The sequel to A Knocking at the Door! Like the actual one this time! If you haven't read A Knocking at the Door yet, I would really advise you to read it now... You would be really confused otherwise! After the skeleton brothers and Toriel have lived in the closest thing to harmony they can manage, their world is about to be changed after a human falls into the underground. (Wow... I summed it up in one sentence... Well, one sentence without spoilers that is! It's gonna get pretty crazy!) (Cover is temporary (hopefully) before I can make one, but this art does not belong to me)
