    Summary

    Set after the events of MyTale. The multiverse holds limitless possibilities, and multiple chances to do things over. Maybe struggling to do things right will build the path toward redemption? Or at least give some closure to a guilty and troubled mind.
    Multiple fourth-wall breaks. Self-insert as Frisk. Some suggestive stuff here and there, but no romance that's out of canon. Can be read as a stand-alone if you don't mind spoilers.

    Summary

    Alphys was sure that this time —please, just this once— everything was going to be all right. The machine she took so long to create would give positive results, help in that conflict, and things would change for the better. And she got all the expected results... or almost.

    Or where a machine malfunctions and the Underfell characters see themselves in human flesh. And they will apparently watch themselves.

    Summary

    Frisk, from Underfell (more recently from Underswap, even more recently from Dancetale, We Don't Talk About Frisktale, and most recently from Swapfell, with a brief pit stop on the way), has finally found a way to stop their endless crash-landing through parallel universes. One more universe, one more life—with no second chances. This time, they're making a home for keeps; with all the trials and triumphs that entails.

    Sans has been in a time loop for a while now, because of that one flower. He's almost through with that, hooray, but there's another one coming, which is too bad. Especially with how that one ends in the destruction of all timelines. Kind of a bummer. But, hey, at least his coat is clean and his brother is happy. That's about all he can hope for, right?

    Papyrus is kind of standing on a rocky boat, what with training to join the royal guard, and being a Great Friend to Undyne, and Sans being even weirder than his Weird Older Brother Standard; but! Whether in his troubles or in lists of his many friends(-to-be), there is always room for one more!

     

    Sequel to And Whither Then? I Cannot Say.

    Summary

    With their happy ending secured, monsters living happily on the Surface, and his marriage to Frisk (and his brother's engagement to that spiteful brat, Chara, though he's reluctant to count that as a good thing), Sans decides that now is the perfect time to confront, and try to resolve, his one, last remaining problem: fixing his father's broken machine and bringing W.D. Gaster back from the Void. But, like everything in his life, things don't go to plan, and there are some unforeseen consequences...

    Summary

    “Well, fuck you Ink.” You hissed, narrowing your eyes and barely controlling your desire of shattering the polished rock against the floor to liberate your anger.

    You were the player, you were the author; You were also Dust, from your own AU. But it seemed that you were trapped in his human form. Which, unfair. Because although you were human it feels icky to have skin covering your bones.

    It was obvious that you were more Dust than Y/N.

    Summary

    This is a collection of stories and one-shots that would make too much work to make separate books for. There will be multiple ships and AUs in this so if you don't like the ship and/or AU then don't read or skip to the chapter you want to. Comments are appreciated so I know how you all are enjoying or if there's something that needs to be fixed.

    DISCLAIMER: I do not own anything used in this book the only thing I own is the ideas to write about. All credit goes to their rightful owners.
