When Faith Lorrell comes across a stopped freight train in the remote San Zechariah Valley, she expects a routine delay—not a wrecked boxcar, a mutilated corpse, and a deadly secret breaking loose into the night. Prehistoric creatures have escaped their transport, and as the body count climbs, Faith is thrust into a fight for survival.

Hunted by both the rampaging dinosaurs and the ruthless corporation desperate to hide its crimes, Faith forms an unlikely alliance with a reluctant employee… and a surprisingly docile triceratops. But the true nightmare is still ahead.

A razor-fast raptor prowls the night, but it’s merely a prelude to something far worse.

Because the valley belongs to the apex predator a fifty-foot Tyrannosaurus Rex!

Over fifty feet in length, it has the strength to wreck buildings, flatten vehicles, and pulverize flesh. Armed with powerful jaws and a bad temper, it seeks to rule the valley, for it is a cruel Tyrant.
