A Margin in Time — Laura Hayden

Framed for an embezzlement he didn't commit, J. Barrett Callan V's only hope of saving the family fortunes is to travel back in time --- to the wild west!

As the spitting image of his great-great-grandfather Johnny, Barrett soon discovers there's more to being a frontier sheriff than he realized. He can't ride, shoot, or spit worth a darn. Nor can he resist free-spirited schoolmarm Emma Nolan. Emma knows there's something different about Johnny, and it's starting to do strange and wonderful things to her heart!
