I have to admit that it didn't live up to my expectations. It felt it was lacking something. And I don't know if it's because I read Devil in Winter first (which was very good!) but it seemed it spent too much time trying to set up the next book in the series. 
 I wanted to know more about Westcliff, his past and his emotions throughout the novel. Instead of a simple summation of his history and affections in neat, orderly paragraph during the latter part of the book 
 Also I was bothered by the library scene. If Westcliff was half the respectable gentleman the author made him our to be, then he wouldn't have taken advantage of Lillian in her drunken state. And contrary to what Kleypas had us to believe, with Lillian that inebriated she couldn't possibly have stopped from sleeping with him even if she didn't want to. Especially taking into account the way she reacts to St. Vincent's advances. She may not have really wanted him, but her character became one of a complete tart. With a lesser author this would have smacked of bad taste. Although Kleypas doesn't fall under that category and all in all this one was still a good read.
