Summary
Frisk Starling should've been used to cases like these. After all, it was her duty to investigate. Give the victims their voice back, catch the sick freak who did it and give the broken families the justice she couldn’t have for herself.
That is until a string of murders throughout the county begin to appear. Women used like toys, mutilated and disposed of for the cops and journalists to find with only the tiniest slivers of useless evidence and the glaring fact that all the women...
Every…
Single…
One…
Look almost exactly like her… Frisk begins to wonder if maybe… the monster she's hunting down has turned her into the hunted.
And God, does she make the most exhilarating, delicious prey yet…

Summary
When it's good, it's great. Really great. But it's those little things that begin to chip away at her heart. The way he sighs when she mentions the laundry. The way he's turned her into the nagging woman. It's hard to believe he cares...
She just wanted him to care.

Summary
It had been a long couple days since they'd split town, hundreds of miles of asphalt and hours and hours of cramped, stale car air between them and home. Benson needed to stop for the night, to get some sleep in a real bed. They both did.
(“You can change your mind,” Benson said, hand lingering on the gun as he leaned over Randy.
Randy stared up at him, his voice only wavering slightly when he said, “Come back. Please?”)

Randy gets off with Benson's gun in his mouth.

Summary
Frisk didn't want to be this girl again—the one who drew along the joints and divots of Sans' neck as he slept, to comfort him, because he hurt her. The one who was bitten and offered her hand as a meal. She thought she had grown past that, had found some indelible worth in herself, some higher purpose, a status that gave her immunity to the belly-showing instinct she was born with. But she loved him. He wouldn't let her love anyone else.

Bookmarker's Notes
It's a difficult read, but I see it as an Undertale version of Fire Walk with Me; a very depraved story that doesn't pull it's punches, but also is very honest about the story it's telling. Frisk would love Laura Palmer.
The writing style is wonderful and while this story fills me with anxiety at even the thought of reading on, I still can't stop turning the page.

Summary
"Frisk is sixteen but Sans never counts it as sixteen. He counts sixteen, seventeen, eighteen, or subtracts the sixteen from the eighteen and leaves two."
Frans but not Frans. Please read the tags.

Summary

But when he discovers that he's endeared himself to her a little more than he meant to, he's faced with a choice: play the part of Frisk's doting boyfriend, or risk her resetting the world and endangering everyone's futures? (Updates sporadically.)
