Transported back in time to the prehistoric era by Time Safari, Inc.—a company that offers time travel to hunters—Aaron Cofield and Jennifer Mason must flee across the millennia, pursued by a psychotic member of Time Safari. Reprint.

A time-travel work evolving from the work of Ray Bradbury follows Eckels, a psychotic time traveler, as he is transported to an alternate prehistoric period by a savage timestorm. Original.

Eckels, a psychotic time traveler, has shot a dinosaur and meddled with history, destroying the future and trapping himself in the past. Transported to an alternate prehistoric period by a savage timestorm, Aaron Cofield manages to link up with a Travis, a lost Time Safari guide. Together, they must hunt down Eckels and restore the shape of history. Attacked by sentient dinosaurs, Aaron and Travis escape to an alternate medieval Japan. Caught between dinosaurs, ferocious samurai warriors, and the cold-blooded Eckels, the two must fight for their own survival-and to restore the timestream of our future!

In the fourth in a series of time-travel adventures, Aaron Cofield and his friends find themselves subject to a constantly changing past, and wind up in Aztec Mexico, where they must flee from Indians, dinosaurs, and Spanish Conquistadors.
