Engaging the Enemy — Heather Boyd

A lady should be the image of elegance and calm, but those words have never applied to Mercy, Duchess of Romsey. A widow and mother, Mercy is lonely and floundering to keep the estate afloat. When she discovers the existence of Leopold Randall, her husband's estranged cousin, Mercy immediately offers to help him locate his missing siblings if he helps her return the estate to order.

Leopold has returned to Hampshire for only one purpose -- to learn the fate of his missing siblings. Unfortunately, the current duchess is clueless and out of her depth. Her struggle tugs at Leopold's sense of duty and her bold nature tempts him unbearably. When Leopold discovers their lives are forever entwined, he vows to protect Mercy and her innocent son.
