(Has been rated #1 in Frans more than 10 times since April 2018) It's 210x, and nearly eleven years after Sans' " ignorant " deed. Little did anyone know it would be the year when the human has mysteriously fallen again, though the seven human prophecy had supposedly been fulfilled. "Seven humans shall fall... Only one will enter and exit alive." By this time Frisk is a growing young lady and Sans is a young man, now working as head scientist for the royal family, along with Gaster and Alphys as his assistants. He is more than happy to see his old friend and she is welcomed with everyone's opened arms. That is...Until she is proven to be something a little more than she appears to be.... Join Frisk as she slowly uncovers the underground's forgotten past and her own dark side, hidden deep behind her DETERMINATION. ((This is an original AU by EkoingSkies. Warning! The main ship in this is Sans and Frisk! If you wanna read this, be sure to keep that in mind. This is my first book, so I would love to hear your interpretations of it! COVER ART BY @LunearTea Check out her account ya'll. She's amazing, I kid you not. ~ Love Ekoing))

A/N: Frisk will be identified as a sixteen year old female in this story. There will also be Frisk x Asriel, but that's not the main pairing. All Characters belong to the brilliant Toby Fox. Enjoy! :: PROLOGUE :: Frisk was a simple girl. She was quiet, didn't ask for much, and always held a look of unshakable determination in her eyes. Ever since she'd fallen to the UNDERGROUND four years ago, things around her had changed. She was no longer surrounded by people who neglected her existence like the humans; instead, she showed mercy to the monsters of the underground, who in return welcomed her with open arms. The once young human girl, Frisk, had, over the years, become a beautiful teenaged girl who taught the monsters the many things she could remember about the human world. Asgore had given up trying to reach the human world, seeing as how everything had seemed to settle peacefully. But when she's faced to deal with the coronation of Prince Asriel, how will she deal with it when she doesn't know how to sort out her feelings?

So...my first book. YAAAAAY...god I'm gonna screw this up. Heheh! ANYWAYS, hope you enjoy this! This is based off my OTP and the game Undertale. If you do not enjoy Sans X Frisk, then do not read it. Don't post mean and totally irrelevant comments. If you don't like, then just don't bother reading my stupid obsession! >:3 NOW THAT THATS OUTTA THE WAY, LETS BEGIN! NGHAAAAAAAAAAA!!!

When a ghost falls in love with loser geek, Amy Rose, it'll do anything to make sure she's happy. Even if it has to kill everyone that gets in his way.

Frisk has had a hard life. Abused by her parents because she is "a mistake." The reason why her parents call her this is because: She is a Neko. Half human half cat. Frisk has been experimented on. Some of them would hurt her or mess with her thoughts for a period of time. It seemed like no one cared. One night, Frisk had enough. She ran until she got to Mount Ebott. By surprise, Frisk tripped and fell down a hole...the entrance to the UNDERGROUND. Though things seem bleak, Frisk gets help. Meets new friends, and possibly develops a crush. Will he feel the same way? Or shut her off like the others on the surface did?
