Always In My Heart — Donna Valentino

SHOTGUN WEDDING
One minute Matt Kincaid was negotiating the business deal of his career --- the next, he was getting married in North Platte, Nebraska, a century past, and with a bullet in his shoulder!
It was an accident. Shooting him, that is. Kate Monroe knew she was taking advantage of the situation by marrying the wounded man. But she was desperate to stay out of jail, and she vowed she'd make amends.
But Matt had other problems, such as getting Kate to say the words that would return him to his own time. He also had some wrongs to right in order to help Kate fulfill her dream of joining Buffalo Bill's Wild West Show. And falling in love wasn't helping matters at all . . .
