When the widowed Lord Torrington agreed to spy for the crown, he never planned to impersonate a highwayman, let alone rob the wrong carriage. Stranded on the road with an unconscious young woman, he is forced to propose marriage to protect his identity and her reputation, as well as his dangerous mission. Trapped not only by her duty to her country but also by her limited options as an unwed mother, Miss Elizabeth Cantrell and her infant son are whisked away to Middlecrest Abbey by none other than the elder brother of her son's absent father. There she is met by Torrington's beautiful grown daughters, a vicious murder, and an urgent hunt for the missing intelligence that could turn the war with France. Meanwhile she must convince everyone that her marriage is a genuine love match if her new husband has any hope of uncovering the enemy. Determined to keep her son's true identity a secret, Elizabeth will need to remain one step ahead of her fragile heart, her uncertain future, and the relentless fiend bent on her new family's ruin.
