Geller's Find

It's summer break and Dr. Luke Geller, history prof and part-time archeologist is in Nevada looking for potsherds. What he discovers is an antique rifle and a portal in time.
Touching an ancient piece of Chiastolite crystal, the earth rumbles, the skies darken and the ground opens. He's hurled straight to the core of the earth then shot back up and spewed out.
When he stumbles to his feet, he finds himself where he began. Same, yet different. There are no winding roads. No parking lots. No cars. No town with bright lights in the distance. Only Lily Winter Tremaine, an angry young woman pointing a gun at him, demanding he hand over her rifle.
All thoughts of primitive pottery disappear as Luke finds himself fighting alongside three young women trying to hold onto their ranch against a dangerous scoundrel who intends to have the ranch by whatever means possible. Then there's the little fact that Luke's mightily attracted to the young woman he's working for. A woman old enough to be his great-great granny. And Miss Lily Winter Tremaine does not figure into any of tenured professor Luke Geller's lesson plans.
