After growing up as an orphan, Josiah English wants nothing more than to have his own ranch and raise Arabian horses. Riding for the Pony Express seems like the ticket to his dream. And when he meets the stationmaster’s beautiful sister, it seems he may be within reach of the happy life he craves. Mara Reid is thrilled to finally meet the man of her dreams, and the fact that they both want to raise horses in the Sweetwater River valley seems like confirmation straight from God. But when the Express shuts down and Mara's family home is in peril, the danger looming over Mara's life may not be half as destructive as that threatening her heart.
