In 1850, as America is torn by civil strife, Becky Foster has dedicated her life to helping runaway slaves escape to safety though the legendary underground railroad in the silence of the night while Indiana's farmers sleep.

Since the death of her husband, the brave beauty has lived for her perilous work. But when she meets Mike Ryan, a rugged drifter with a dark past, she begins to long for something outside of her secretive work for the railroad.

Despite her desires, Becky continues to fight her attraction to the tall stranger. Even as she melts into his embrace, she knows she cannot reveal her secret--if she loses her heart in such treacherous times, she will put hundreds of lives at risk.
