    Summary

    You went to the bookstore one day to buy some manga.

    You got a whole lot more than you bargained for.

    You end up somehow saving the Royal Scientist's life, and her fiancée can't thank you enough for it.

    So that's how you find yourself surrounded by people who love you for who you are and don't want you to change.

    But what's up with these strange dreams you're having? And, why does a certain punny skeleton get so spooked at the number 17? And...who is that tall skeleton with cracks in his face that you keep seeing in your dreams? Did the ambassador of monsters just join your swim team? Can this summary get more cliché?

    This is my first fanfiction on AO3, so constructive criticism is appreciated!

    Summary

    You're a modestly successful fiction writer living in rural Alaska; just you, your dog, and your horse in a small cabin on a large piece of property in the shadow of a mighty mountain range. You're used the the quiet, enjoy it even, but when you start having recurring dreams of a strange skeleton visiting you in the night you wonder if the solitude might be starting to get to you...at least until you realize you're not dreaming at all because Sans is, in fact, a real, live monster. Friendship, romance, and shenanigans ensue.

    Summary

    This was a horrible idea.

    And yet here you were walking towards the event halls doors, a flame monster tailing closely behind. As you reached the door you waited for the explosion of shouts and rushing of feet to stop you from leaving with a monster in tow. Nothing came and you continued out into the lobby with no resistance.

    This is a story about dear reader being in the wrong place at the wrong time and meeting the right person... for once. Can things work between you and a fire elemental in a world where monsters are seen as nothing more then tools?

    Summary

    MonsterBook est l'équivalant de Facebook pour les monstres, avec quelques différences. Les personnages d'Undertale, dans leur fin hyper-pacifique l'utilise beaucoup. Surtout les enfants Dreemurrs, qui ont parfois des idées un peu bizarres.
