An intelligent Dromaeosaurus named GerG (or maybe just an actor playing GerG in a story, it’s hard to tell), prepares to travel 70,000,000 years into the future in order to pave the way for all the soon-to-be-extinct dinosaurs to escape.

By the halfway point of the story, Gordon Redcliff (angry, jaded ex-military sniper and bodyguard) is stranded in a primitive civilization 140,000 years in the past, and he must face the question of whether the widow he’s falling in love with is enough motivation to violate his directive to not interfere with “one hell of a disaster coming in just a matter of a few months.”
