Summary
It’s been 15 years since the land became inhospitable, or at least that's what everyone knows. The world is nothing like it once was, and Bonnibel Burke understands that. She was only ten when civilization started to collapse. Now, she lives in the last surviving city, slaving away day by day to survive. It’s hard for Bonnibel to find joy when she knows that teens are being ripped from their families just to become another number in the work field. There’s also little that gets past the government, as there’s a camera around every corner. Bonnibel knows the rules regarding the outside land and the “Old World,” but what will happen when she has no choice but to face the reality of her situation? Is there a way to get around the government, and avoid being reborn?

Summary
The Winter King is dead, leaving nothing but the flooded plains where his castle used to stand... and a very confused Marceline, returned to her adult body but still made of ice. Bonnibel isn't sure what to make of it, and she's dealing with her own trauma after being freed from her curse of madness and coping with the total destruction of her kingdom.
But everything will be fine, because she's going to fix Marceline... until a second Marceline shows up, claiming to be the real deal. Unwilling to choose between the two, the three women have to learn to deal with their strange new circumstances while navigating their shared traumas.

Summary
Three hundred years ago, in the Land of Ooo, a girl pretending to be a monster met a monster in the process of becoming a girl.
They have very different ideas about what they want from each-other. Different ideas about everything really. It's hard to think of two people more opposites. So you'd think it could never work out between them.
It doesn't, at least not this time. But they both learn a lot of important lessons finding that out.
Mistakes are made, emotionally wrought songs are written, a kingdom rises and various unusual sex acts are attempted.
It's an adventure for everyone involved.

Summary
Sometimes I just start writing when I'm sad or bored and yesterday I realized Dean loves Pie and Tree Trunks loves to make pie and I'm like it's time to write. Usually with a comedy story like this I write it all in two hours and post and never look back but I reached a writing block...maybe cus this is even to far for me..but I'll probably continue it soon and see where it goes. I'm positive Castiel will show up at some point too. Lol.
Ok it is done. You're welcome or I'm sorry idk.

Summary
After Jessie is taken by a vampire, a familiar grey face from Ellie's and Joel's past appears in Jackson, opening the door to a world of magic and weirdness in the harrowing ruins lining the way to a snowed-in, partially frozen Seattle.
In the Rattler's lair, Abby sees a horned figure standing in the hospital room of her dreams, its face mangled, its voice deep and beckoning with power beyond her imagination. It might be enough to protect those close to her, but will it be worth it?
Vampires. The Crown. Infected. Bass music. Green flame.
Magic.
Mostly takes place after the opening chapter of the Last of Us: Part II, in a world where the Mushroom War didn't happen - but mushrooms still messed up the world.
