Silver-tongued Viscount Sanburne is London's favorite scapegrace. Alas, Lydia Boyce has no interest in being charmed. When his latest escapade exposes a plot to ruin her family, she vows to handle it herself, as she always has done. Certainly she requires no help from a too-handsome dilettante whose main achievement is being scandalous. But Sanburne's golden charisma masks a sharper mind and darker history than she realizes. He shocks Lydia by breaking past her prim facade to the woman beneath...and the hidden fire no man has ever recognized. But as she follows him into a world of intrigue, she will learn that the greatest danger lies within -- in the shadowy, secret motives of his heart.
