Aurora and Apollo's story is one that is now, unfortunately, very relevant. Aurora is one of the few women physicians who performs clandestine care and procedures. Apollo is a newly member of the peerage who's trying to find his place in the world. Sparks fly when they meet and they start to recognize that the idea they had of each other is not all that appears. This book made me emotional because of the current state of women's rights to their own body. The romance although spicy, is secondary to her work and his wish to keep her safe. 
Adriana gave her characters the perfect humanity to make them relatable. It was a fitting end to the series.
