A Creepy Boss

Youve excused yourself to the bathroom during another gallagher at the bar. Your reflection is staring a little bit too hard at you from the mirror. You question if theres something actually there.
Are you possessed? Is this mental affliction demonic? Or does it just feel like it is? Our protagonist Laura hasnt a single clue and is powerless against its influence
She doesnt realize it, but her world is falling apart. A novella not for the faint of heart.
