A fiery heroine teams up with a gruff detective to catch a thief, but the real danger may be trusting each other. With her family nearing destitution and her home on the brink of foreclosure, Carina Clarke has little left to lose. Yet in one fateful evening, the 1871 Peshtigo Fire destroys the last of all she holds dear and separates her from her sister and friend. Carina vows to find them—even if it means moving to a different city and taking up work at a textile mill while she searches. Oliver Ramhurst is determined to make his father proud of his work as a Pinkerton detective. His assignment to capture a thief at a textile mill in Milwaukee, Wisconsin, could be the opportunity he needs—if the feisty Miss Clarke will stay out of his way. When the clever woman offers to help him ferret out the culprit, Oliver reluctantly agrees. But does she want more from him than she’s saying? As the danger grows and they draw closer to discovering the true identity of the thief, Carina and Oliver realize that nobody is who they seem. Carina must decide who can be trusted and who may be a villain in disguise—for when the hour grows dark, trust may be the only thing that can save her.
