Undertale:Secrets
Remaster on my page - check it out! Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that he wishes could remain a secret. But when the questions start being asked, what does he do? These questions seem so little, yet they cause so much to happen. One little question. "Who is ??????" can change so much. A chain reaction from a single sentence can cause an entire world to crumble. Or maybe two. This is my first book so dont expect anything great.

Wisdom. Book 1 (Warning! Contains spoilers of Undertale! kinda...)

ShatterTale
A FanFic Version of Undertale, created by Toby Fox. In this universe, Frisk was the sixth fallen child-and unlike in the original timeline, they failed. Whether it was because they were too merciful in a place that demanded strength, or because the Underground broke them, Frisk died at the hands of a major character (Asgore), and their SOUL was shattered before they could reset. Kael is the seventh fallen child, but unlike the others, they didn't fall trying to escape something or out of curiosity. Kael fell by complete accident-a cruel twist of fate, perhaps pulled by the very magic that keeps the Barrier sealed. As if the Underground itself needed one last soul to tip the scales.Complete
Hungry Love (Horror Sans x Reader )
In the midst of Tokyo's bustling streets, you led a life that appeared ordinary, despite your role as a leader in a prominent gang. Yet, beneath the façade of normalcy, you carried the weight of profound loss-your mother, your father, your brother-all taken from you, leaving behind a void that seemed impossible to fill. Determined to shield yourself from further heartache, you resolved to protect the one remaining person you held dear: Frisk. Their presence brought light into your shadowed existence, offering a glimmer of hope amidst the darkness of your past. But fate had other plans. The dissolution of your gang shattered the fragile stability you had built, leaving you adrift in a world that suddenly seemed hostile and unfamiliar. Yet, in the aftermath of this upheaval, you found solace in Frisk's unwavering companionship, their presence a beacon of comfort in a sea of uncertainty. Then, in a cruel twist of fate, you lost Frisk. Cast into the unfathomable depths of the underground, your path collided with Aliza's, a chance encounter marked by the ominous presence of Horror Sans. Emerging from the shadows, his hollow eye sockets bore into your soul, his grin sending shivers down your spine-a chilling reminder of the darkness that lurked within the depths of the unknown. With each loss, the world seemed to grow colder, more indifferent to your struggles. Yet, amidst the despair and desolation, a glimmer of resilience flickered within you, a quiet determination to reclaim what had been taken from you, no matter the cost.![Is This Real? {Sans x Frisk} [COMPLETE]](https://img.wattpad.com/cover/77967985-256-k179594.jpg)

The Human Underground book one: Magic knows no bounds
Alisa was only a little girl when she and her two canine friends fell into the Underground, only ten years old. Eight years past since she fell and the girl was glad she did. Her past could not get to her here and everyone was kind and accepting of her. She couldn't let them know of her secret though. They would hate her and hurt her and Alisa wouldn't be able to fight back. Word gets around eventually to the skeleton brothers and Sans gets curious. Who is this strange human and why were they different than the rest? Not wanting to go back to the surface? This is a story of friendship, family, and love. Though, magic has something to do with all of that though... SansxOCComplete
