Honestly, while the sex scenes were seductively hot...vanilla...I began to think this was more erotica than romance. And the only thing historical about it was the pretense of the setting. The sex starts immediately and is the primary storyline through the first 2/3 of the book. Finally, the story asserts itself near the end, but it is a jarring transition, to say the least. One sex scene after another for more than half the book, then...
Well, it's worth a credit... Decent writing. Decent entertainment.
Tarquin is wonderful. Sexy, strong, intense, he quickly realizes his attachment to Diana and that his feelings are growing stronger instead of being dense as so many heroes. In spite of her continually callous and selfish behavior he manages to see through a lot of her machinations and love her anyway. And Diana is one of the worst heroines I've read about in recent years. She's greedy and self-serving for no given reason (it's not like she was faced with poverty or in danger), lies at every turn and literally waits until the eleventh hour to do anything decent or thoughtful. Five star hero matched with a one star heroine makes for a three star read, unfortunately.
