The Irresistible Allure of a Lady Spy: A Historical Regency Romance Book by Henrietta Harding

I loved this story. Both main characters are wonderful and want more from life. Mary is willing to risk herself to help Isaac, but doesn't realize that she is also risking her heart. Isaac wants to be a better spymaster and wants to get the information that they need. Isaac takes up Mary's suggestion and uses Mary to get the information. What Isaac did expect was losing his heart to Mary. There are lots of complications and the story plot follows through to the end.
