    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)

    To protect your secrets, how far are you willing to go? This is the dilemma that Papyrus, the royal guard's captain of Snowdin town is facing since he accepted to protect the last fallen child. What he thought would be a simple task is slowly driving him away from his guard's duty, at the worst time possible. When he finally understands something is really wrong with Undyne, his rival and only friend, it's too late. Overnight, the general announces to him that he is now in charge of the royal guard and disappears from his life. Even if he tried, Papyrus couldn't resolve himself to let her go without knowing why she gave up on everything in one night. However, by trying to dig out too many secrets, Papyrus has to face a lot of problems. Threats, intimidation, someone is trying to force him to give up. But the more he searches, the more he realizes all the tracks lead to Asgore. The King is known for his impeccable justice and his absence of mercy. If he doesn't give up, he might lose way more than just his job. Split between his vocation and his friendship, Papyrus will have to make a choice.

    [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!
