Callie Collins, a proud woman in the late 1800's, is a liar and a darned good one, a master of the dubious art. She is also a dreamer. Her greatest hope is to reach a new life in South Pass City, Wyoming, where she can open a bakery and live an independent life. To be successful, she will need her greatest deception to date, a mythical fiance who waits at the end of the line. As a woman alone, she has to prove to Seth McCallister, the wagon master, that she has the wherewithal and the stamina to survive months of drought, dust, hardships, and even the risk of death.Seth McCallister is mystified by the audacity and determination of Callie Collins. His initial distrust and concern for Callie, a woman traveling alone, opens first to admiration, then friendship, then love, a love that he is forced to hold at bay. What he doesn't realize is that there is no fiance. To make matters worse, Callie develops feelings for Seth McCallister, too. Yet she feels certain that once he realizes her deception, he'll turn away, ashamed of his love and trust in her.
