Under a carefully crafted lie, Anna has gathered the people responsible for her family's ruin aboard a lavish overnight train from Philadelphia to Chicago. It's a thirteen-hour journey-and by the end of it, she plans to expose their crimes, force confessions, and hand them over to the authorities waiting at the final stop. For Anna, this is more than revenge-it's justice long overdue.
But her plan goes off the rails when one of the passengers turns up dead. Trapped in a moving train with a killer on board, Anna quickly realizes she's not the only one seeking retribution. Someone else is eliminating passengers one by one, and they won't stop until no one is left alive.
Now, with time running out and bodies piling up, Anna must unmask the murderer before they reach Chicago. To take down her enemies, she'll have to protect them first-even if it means risking her own life to do it.
