A catastrophic train derailment. A dying stranger. A flash drive worth killing thousands to protect.  Lena Ward boards a late‑night commuter train to escape a night gone wrong—only to wake in the middle of a nightmare. Moments before the crash, a bleeding man presses a metal flash drive into her hand and whispers a warning that will upend her life:"e;Don't trust anyone."e;When the train is violently sabotaged, Lena becomes the only survivor who knows the truth—and the only witness carrying evidence a secret organization cannot allow to surface.
