Time is money. In a world where the wealthy can rewrite the past, someone has to pay the bill.
Elias Thorne is a Temporal Marshal who is tired of the taste of copper and the weight of a badge that means less every day. In an era when the wealthy commute to the past to fix a mistake, close a deal, or relive a memory, Elias is the janitor who cleans up the timelines they break.
He just wants a day off. He books a seat on the Ouroboros 9, the flagship train to Yesterday, expecting a quiet ride and twenty-four hours of peace.
He gets neither.
When a desperate neurosurgeon smuggles a reality-fracturing device on board, and a billionaire industrialist hijacks the engine for his own gain, the train is knocked off the rails of history and into the grey, silent wasteland where aborted timelines go to die.
Trapped in the void, Elias discovers the terrifying secret fuelling the Ouroboros Corporation's engines. It isn't magic. It isn't electricity. It is a resource far more finite, harvested from those who can't fight back. To save the passengers, stop a monster, and return to the real world, Elias must pay a toll that no amount of money can cover.
He can save the future. But at what cost.
Blade Runner meets Murder on the Orient Express in this gritty sci-fi noir about the high cost of second chances.
