KAIDIE HEITH, a young bowling-alley attendant in rural Pennsylvania, spends her days in a haze of fluorescent lights, sticky rental shoes, and the monotony of resetting pins for people living fuller lives than her own. She aches for something — anything — that might shatter the grayness of her routine.

Her wish appears in the most unlikely form: a strange bowler couple who approaches her with an unsettling familiarity. Kaidie soon learns they are part of a clandestine circle of rogue scientists on the brink of unveiling a radical “new mode of living.” But their discovery comes with a price — and a target.

They are hunting Satan himself.

Drawn by desperation, curiosity, and the promise of meaning, Kaidie agrees to join them. What follows is a perilous odyssey through time, as she chases a demon whose influence has warped some of history’s most dangerous and notorious figures. Every era she visits brings new threats, new temptations, and revelations about the true nature of the scientists guiding her.

But the closer Kaidie gets to the truth — and to the demon they seek — the more she realizes she may be little more than a pawn in a game older than history.

If escaping her gloomy life requires defying Hell itself, she is ready to pay the price.

But can a bold, rebellious young woman truly rewrite history… and save millions of lost souls?
