Loved the book. Read the majority of it when I should have been sleeping. Couldn't put it down. What made it a 4 star vs a 5 star book for me was the lack of contact and connection between the 'heroine' and the 'hero' because of the amount of POV change-ups. If you can call the change of narration when it was in 3rd person a POV change-up. A better way to describe it: there were too many people being narrated about, taking away from the main characters. Yes, I want to connect with the characters that will grace subsequent books as the protagonists, but not to the detriment of the current one. Too much going on in the setup of the series. It needed to be weeded out and simplified (I can understand complex storylines.;) too many cooks in the kitchen, so to speak) 
 Highly recommend to lovers of Historical Romance. 
 Yes, I will continue on with the series, as well as finishing off Ms. James' backlist of works. I've got a lot a reading ahead of me to tackle that list! :D
