She's been running Hell like a well-oiled machine for 10,000 years. Scheduling tortures, organizing plagues, and keeping Lucifer himself on track, life as the Devil's personal assistant isn't glamorous, but it's predictable. Until a "demon flu" outbreak leaves her forced to torture souls herself... and one babbling human changes everything. Suddenly, she's sneaking into prison cells, laughing at stories about toothbrushes and rollercoasters, and asking the one question no demon ever should: what's it like to be alive? When the Devil refuses her, she takes matters into her own claws, kidnapping the soul and stealing a human body to experience Earth firsthand. But between terrible coffee, confusing slang, and the chaos of living with her new human roommate, the Devil's PA is about to discover her hardest job yet: surviving the real world.
