    Summary

    (Y/n) lost her job, which sucks. If only she hadn't lost her second job, and apartment, as well! Now all she's got is a camper full of her crap on the back of her truck, and nowhere to go. At least she found this campground, even if it is in the middle of nowhere, and looks like no one has been around it for a while, and a skeleton with a head wound tries to make her into a meal... Rough start to making new friends, but his brother is sweet enough!
    And then there's the other skeletons who inhabit the other cabins, who all look vaguely similar... Their explanation of "cousins" only goes so far, but there are more concerning things to worry about, like how almost every skeleton is trying to get into her pants, their heats, and where her clothes, particularly her socks, keep disappearing to?!

    Summary

    “Fuck,” it hit her, suddenly, that this wasn’t her home, this wasn’t her body, that this wasn’t even the vanilla timeline, or a happy alternate timeline, that she had expectations weighing on her shoulders, that she had to tread carefully or risk death, “Fuck!”

    Summary

    A drunken night you can't remember leads you to wake up in the very large home of a very large family of skeletons. You try to escape their grasp and pretend like nothing ever happened, but for some reason, they're determined to befriend you. Some try to get a little too friendly. Some don't like you at all.

    But when disaster strikes your home and you have nowhere to go, they're more than happy to lend you their dusty attic. You don't even have to pay rent. What's the catch?

    Oh. That. Well you suppose you could do that if it means having a roof over your head.

    Summary

    Razz has had a very rough go on the surface. Between his racist coworkers, psychological issues and his brother’s waning loyalty, he’s been finding the days harder and harder to get through.

    Will he be able to repair the damage caused to his and his brothers relationship? Or will he fall under the pressure of living a civilian life?

    It may take help from an unlikely, extremely fuzzy source, to get there. (Warning: lots of cat fluff is ahead)

    Summary

    Sweet, kind, quiet, loyal. Those are the words you would use to describe your skeletal friend, Hound. They were values anyone would adore to have in a significant other, and while you had both dated for a while, there was something missing. Something you longed to see and yet dared not ask.

    What you hadn't counted on was just how observant your datemate was...
