Masquerading with the Duke by Wendy Soliman

Summer 1826
Tired of having his loyalties constantly questioned as a consequence of his father’s nefarious activities during the war with Napoleon, Jared Braden resigns from the diplomatic service and returns to England during one of the longest heatwaves in living memory. He purchases a rundown estate close to the home of Redrow, the cunning individual he suspects of being the real traitor working against British interests.
Martina Sanchez-Gomez, one of two Spanish refugees rescued from an uncertain future by Lord Amos Sheridan, leaves her position in the Redrow household without explanation. She joins her sister at Winchester Park, the opulent home of Zachary Sheridan, the Duke of Winchester, where she is thrown together with Jared in a most unexpected manner. Martina feels an immediate connection to the duke’s handsome new neighbour. When she discovers that they both have reasons to dislike Redrow, Martina explains to Jared why she left the man’s employ.
When an opportunity to help him restore his reputation arises, she doesn’t hesitate. But on the night of the duke’s sophisticated masquerade, Martina’s recklessness puts her life in danger. Will Jared succeed in clearing his name and find a way to save the woman who has come to mean so much to him from her own impetuousness…
