I'm looking for a story

Dear Reader(s),

To anyone who feels inclined to respond to this, I'd like to ask for a bit of help. Nothing major, I assure you, I'm just trying to find a story I saw while scrolling offline-that is to say, not logged into my account-and I'm trying to find it again so I can give it a read. The basic premise is a displaced fic where a bog-standard human woman with no powers or magic or anything else of the sort that a displaced usually gets spirited away with-the exception being a few firearms she had either on-hand or in the trunk of her car(can't remember which)-, but every time she falls asleep, she wakes up in a new world/dimension/universe/whatever-the-hell you wanna call it, and has to survive until the next 'shift' and repeat the cycle all over again.

As for the cover art, I'm fairly certain that it was an image of her standing in front of the tree house library thing... I can never get over how weird it was, but anyways, she was standing in front of it holding a pump-action shotgun in the sort-of "I'm gonna paint the ground pink wit' cha brainz" pose, with one side of the building in the middle of a bright sunny day, and the other one coming straight out of a post-apocalyptic nightmare, a raging inferno razing the town to naught but smoldering ash, embers raining down from the sky as if the devil himself were weeping tears of hellfire and brimstone, and a soul rending blood moon high above the sky, yet slowly getting closer to the world below as the end times near ever closer.

If you do happen to find it, I would greatly appreciate it if you would send the link my way through either a PM or the comments. If not, then please ask around and see what someone else is able to dig up. As for any moderators or admins or anything of the sort, should you ask me to take this down, and provided you can support your claim with evidence and/or a link to the rule book that says I did something wrong, I will do so without any further questions or argument. Please note, I am not trying to be snippy, I simply don't want to violate the rules and be banned from using the site, as there are a lot of fantastic novels on here that I wish to see the completion of.

Sincerely,
