    Summary

    Living on the streets of Ebbot City was hell enough for someone with nothing, that is, until you get picked off the street by the head honcho of the largest syndicate in the Mafia. After saving his youngest son and said son getting attached to you, Antonio Mahoney saw potential in you and raised you alongside his three sons. The Mahoney family gave you everything, a name, a family, a job, a purpose.

    When the monsters were freed from the Underground, it stirred something in the syndicates across the city and in you. The doctors claimed you were healthy but something was off when you were around monsters. Now with them creating their own group and clearing out the little shitty groups that were nothing but trouble, Boss now wanted to make deals, conduct trades, and work with them to stay in their good graces. A smart move considering the magic and Souls ordeal that was flooding the news.

    Maybe, just maybe, you can get some answers from these guys, if they were willing to bargain. Especially that big skeleton- wait, what?

    Summary

    The monsters broke free. Only, they weren't what we had exactly expected.

    Now the monster mafia runs things by their books. I work at a bar in the city where they're most active, and one skeleton in particular has his eye lights set on me. But I'm not going to make it easy for him. He's the biggest name in the mafia, and I'm not gonna just bend to his will just because of that.

    Oh, no. I'm gonna make this drag out until he leaves me the hell alone.

    Or will he?

    Summary

    The law of the Underground is "kill or be killed", so it was easy for monsters to adjust to the systems of mobsters and mafia when they resurfaced. In the midst of the great depression, where only the fittest survive, they have easily climbed their way to the top of the food chain, where monster king Asgore Dreemurr rules the city.

    Frisk; the daughter of a white woman and a black man, already struggles to survive in the cruel world, but when her half-sister Chara becomes the lover of the monster prince, Frisk finds a target painted on her back.

    Enter the skeleton brothers; placed in charge of protecting her from such threats. But they may just end up placing her in more danger, as she struggles to protect their secrets, such as the affair between the older brother and Asgore's wife, or the mysterious circumstances surrounding their father. To add to things, Frisk is finding herself frustrated with her growing crush on the gruff but gentle Papyrus, who's determination to stay kind in the cruel world inspires her.

    Through a mess of power struggles, war, violence, sex, and love, Frisk finds that she can't go back to her old life, but maybe she doesn't want to.

    Rated M for gore and smut.

    Summary

    Frisk had to be either really brave, or a special kind of stupid to stick her nose where it didn't belong. That's what everyone thought when she got herself involved with the Conway Case. Where the police had left it alone, Frisk saw rage, and an opportunity. An opportunity to give justice to a family through the written word.

    But the deeper she searches, the darker the tunnel gets, filled with sharp twists and betrayal. Everything she thought she knew is turned on it's head, and her life is on the line. Things certainly don't get easier when she attracts the attention of the most notorious crime boss, or when Death himself begins to chase after her. Will Frisk unearth the truth of the Conway Murder? Or will she join the ranks of bodies at the bottom of Ghost lake?

    Summary

    Underneath the skies of New Ebbot, one star shines brighter than most. Plucked from nothing into fame, the one voice that graces radios all around croons its suffering and romance to eager ears, dances to complete abandon to hungry eyes.

    You are the unfortunate Private Eye hired to track down and locate said starlet, and make sure he doesn't cause an uproar in every venue he's supposed to sing at by showing up drunk and half-naked.

    Sans "Red" the Skeleton is going to be the death of you, eventually.

    Summary

    "These violent delights have violent ends
    And in their triumph die, like fire and powder,
    Which, as they kiss, consume."
    -William Shakespeare

    Despite your better judgement you agree to start working at the nightclub owned by the local monster mob. You know it’s begging for trouble, but something inside you tells you that this is where you should be. You know it’s only a matter of time before you get burned, you can only hope that is will be at the hands of the purple fire elemental behind the bar.
