Rider's War — Laura Stapleton

She doesn't mind being a spinster...Anna Howard had a problem. On the verge of spinsterhood, she wasn't in any hurry to fix the situation. Except, now the only man she's ever been interested in wants to join the Union army. So if she wants to keep her intended beau in town, she'll have to be either crafty or to let him go.He's a man on a mission, until...Irishman Mason O'Brien figured he had plenty of time to be a Pony Express rider. He'd gallop into Laramie, make an excuse to see the pastor's daughter, Anna, and enjoy life. But when Fort Sumpter falls, and President Lincoln calls for volunteers, Mason feels compelled to serve his new country.Can he go and help put the Rebels in their place with the rest of the United States and be back before Christmas? Or are the more dire warnings true, and he might never return to Anna after all?
