When a brutal murder shocks a quiet Texas town, all signs point to a cold-blooded killer in a black Cadillac with tinted windows and no plates. With no witnesses, no pattern, and no end in sight, Rangers Baker and Tate race across the Texas heartland, trailing a ghost on wheels who always seems to stay one step ahead.

A desperate plea to save a dying son draws Rangers Baker and Tate into Harvest Home — a town frozen in time, sealed off from the outside world, where medicine has been replaced by rituals and children are taken for ceremonies no one dares resist. What starts as a rescue turns into a fight for survival in a town that tightens like a noose.

A victim found inside a sealed home that even the most seasoned investigators can't explain — and every 'perfect' crime is only the first move. Rangers Baker and Tate race against time to stop a brilliant but deranged psychopath whose ingenious locked-room murders grow more impossible as the body count rises.

When Caleb Vance — a magnetic national figure credited with helping elect the President — is brutally murdered in front of his wife and children at a packed outdoor forum, his killer's manifesto spreads like wildfire online, inspiring a string of copycat attacks. Rangers Baker and Tate race to stop a cycle of bloodshed fueled by obsession, fear, and the deadly lure of internet fame.

Burn barrels filled with human remains turn up across Texas, each sparking a new blaze — until the fires merge into a monster inferno the governor calls the worst natural disaster in state history. Ruth knows better: the wildfires are planned, the drifter who confessed is only a patsy, and the real killer is still out there.

A derailment exposes a trafficking pipeline that has been moving human cargo through the heartland for years — and another train departs in hours, carrying children who will disappear forever if it reaches its destination. Ruth boards it, and now she and Aaron are trapped on a speeding train full of killers where there are no scheduled stops, only scheduled deaths.
