"Emily Leverton has spent her life trying to remain invisible. As a young thief on the streets, it kept her safe. Now, as part of a network of governesses who spy on the 'ton', her job depends on her ability to fade into the background. Until one night when she recklessly blows a kiss across a ballroom. And just her luck, she aims it at the one man who could never ignore her. Straddling the worlds of the 'ton' and the working class, railroad magnate Zach Denholm solves cases for the Metropolitan Police by day and dutifully attends balls at night. In neither word has he met anyone as intriguing as Emily--a smart, independent woman hiding more than her true name. The more time they spend together, the faster he falls for the streetwise woman who handles a dagger as skillfully as she kisses. But when their budding romance intertwines with Zach's hunt for a killer, he discovers Emily has an explosive secret--one that could destroy them both."--Back cover.
