I gave this book 3 stars for its clever repartee and funny dialogue. But if I were to rate it on plot alone I would probably give it 1 star. Although the premise is interesting, the execution is poor. The protagonist, Villiers, needs a mother for his many children and has to decide between two aristocratic ladies, Lisette and Eleanor. Supposedly the duke is undecided, though there is NO doubt from the beginning who the ultimate winner is. Somehow all parties meet at Lisette's manor and hilarity ensues. It is clear from the beginning that Lisette is not just eccentric, but totally unhinged and Villiers, a supposedly brilliant man, is unable to detect this. All he ends up doing is parading around aimlessly like a peacock in his ducal finery looking fierce and curling his lip with amazing frequency. Eleanor walks around with the male equivalent of a constant boner and is indiscriminate in her actions. Lisette behaves in a manner not appropriate for a scullery maid, let alone a duchess, yet everyone thinks she is charming. The visit to Lisette's manor is interminable, it drags on and on and I thought they would never go home. The dog, the mother and the sister are equally annoying, all cardboard figures without depth.
Readers are supposed to suspend disbelief in regencies, but even so some of the characters' behavior in this book is implausible even by today's standards. I read another book from this series, When the Duke Returns, which I enjoyed. I abandoned another one, This Duchess of Mine, after reading the sample and did not bother to download. I think I am done with this series.
