Jaimey Grant is a member of the Clever Fiction writing group, and that's where this book had its origins.
"My Lady Coward" is the story of Maria, who is married to a duke named Richard. As the daughter of a Cit (what we might think of as nouveau riche today), she is looked down upon by the nobility into which she has wed.
She's also madly in love with her husband ... and is afraid to tell him since, as with many such marriages, he needed money and had a title to offer in exchange.
There are many plot twists and turns, including an appearance by Hart, the male lead from Grant's Heartless (Grant often includes characters from her other books as a plot device).
The episodic nature of the story is evident, but the book is entertaining nonetheless.
