Regional dispatcher Mae Alvarez spots danger in an impossible detour. Federal cargo inspector Thomas Reed finds forged maintenance orders, false signal authority, and frozen samples from a disease-resistant orchard line stolen from tribal growers. As sabotage closes routes across Nevada and Utah, Mae and Thomas must keep PNR 741 moving without handing its cargo or proof to people determined to erase both.
With a strike choking the eastern interchange and a parallel freight crew trapped in the heat, every decision costs time, safety, or trust. The Orchard Line is romantic suspense built on rail-yard pressure, restitution, and hard-won partnership. The tunnel ahead is dark, the route is compromised, and stopping may be worse than going on.
