I enjoy reading the Bridgerton series but this one just dint do it for me. 
 I loved the blurb. It reminded me of one of the stories in the movie "Love Actually" . So I was looking forward to how this story would progress. 
 Now Francessca's husband dies suddenly and I thought Micheal and her reaction were written really well. The shock, the disbelief, the expectation of Francessca from Micheal and Micheal's stand on being accepted for who he is and not as a crutch for her emotions. 
 I think after that pretty much everything went down hill. Initially Francessca's hesitation in accepting Micheal is understandable. But after that it just got irritating. Similarly Micheal's character to me was very under developed. Every hero in this series is a rake so why should he be treated any differently. Also I did not understand his thought process. He wanted her and he makes up his mind to have her but when Colin mentions marriage he is shocked. So was he looking only for sex then??? 
 The whole seduction and dirty talk does not make When he was Wicked an appropriate reason to name the book so. 
 So overall a 2.5 star for me.
