Facing the bankruptcy of the family business, J. Barrett Callan accepts his great-great grandfather's offer to exchange places in time in hopes he can change his future by fixing the past. But if anything, his troubles compound when he ends up in the mining town of Margin, Colorado as an inept sheriff who can't shoot, ride or spit worth a damn.
There he encounters a "spinster" who serves as the local schoolmarm because the townspeople would never accept her as the doctor she's trained to be. Together, they'll work to keep Margin safe from rampaging miners, crooked investors and a visitor from the future far beyond the 21st century.
"...the first book I've read in years that I wish I'd written."
