Time-traveling turns into big business and big trouble when a casual walk down a farm path in a quiet Wisconsin town leads an archeologist into the Pleistocene era and he uncovers an interstellar mystery from before recorded time ...
Asa Steele is unprepared for the incredible events that begin to unfold when Rila Elliot--a woman he loved two decades before--steps out of the past and his faithful dog Bowser starts loping into it through time trails he's discovered in his own backyard. Rila's appearance is mere coincidence, but Bowser's retrieval of fresh dinosaur bones is as inexplicable as is the curious crater in Asa's backyard that seems to have been made by a spaceship from the stars. And that's only the beginning. Soon Asa himself trips in time, led into prehistoric eras by an enigmatic cat-faced creature. Unable to communicate with his alien guide except through a local simpleton named Hiram, Asa attempts to understand the meaning and the purpose of these time trails. Meanwhile, Rila, always looking toward the future, arranges to turn them into one of the biggest money-making travel ventures of all time.
In short order, the time trails in the quiet town of Willow Bend become the focus of global attention, government scrutiny and the target for an unprecedented solution to overpopulation.
But from the moment the first modern men begin trekking back in time, there's more danger, excitement and trouble than any of them would ever have bargained for.
