Life in the American West hasn't been easy for French refugee Lorraine Durand. She has precious few connections and longs to return to her native land. So when the man who rescued her from a Parisian uprising following the Franco-Prussian War persuades her to help him with a deadly holdup, she reluctantly agrees. Despite his promises otherwise, the gang kidnaps a man, forcing Lorraine to grapple with the fallout of her choices even as she is drawn to the captive she's meant to guard.

Jesse Alexander must survive. If not for himself, then for the troubled sister he left behind in Los Angeles. At the mercy of his captors, he carefully works to earn Lorraine's trust, hoping he can easily subdue her when the time comes. But as they navigate the treacherous wilderness and he searches for his opportunity to escape, he realizes there may be more to her than he first believed.

With danger lurking at every turn, they must decide whether to trust each other enough to plan a combined escape or risk falling prey to the gang's devious schemes.
