I always include major spoilers (hidden), to help with my memory  issues. Read them at your peril! 

If you love long drawn out angst where the hero spends most of the novel believing that he can never have the one woman that he has ever loved, this will be right up your street. As it's a Bridgerton story, their mutual sexual attraction eventually gets the better of them. This comes much later in the story than with other Bridgerton tales though. As ever, the wider Bridgerton family add humour and continuity to the story. 

Francesca née Bridgerton has not long been married when her beloved husband suddenly dies . His cousin and their best friend, Michael, has been in love with her from first sight  and cannot bear the guilt of inheriting John's estate whilst still loving Francesca , as if he has somehow wished this to happen. He goes abroad for several years, returning just as Francesca is ready to start looking for a second husband, only because she wants a baby .
