I really enjoyed the second installment in the series. We got to learn more about our characters and we got a few little insights into things to come. 
 In this book we get an introduction to the shifters who will be playing a bigger part along the way I feel. I think that the whole mystery plot was nicely conceived in this book. Since the first book was mainly an introduction for Merit's new life as a vampire I don't think the mystery was as focused in that book. I think in the first book there were more questions raised about future occurences than having an actual mystery storyline to follow and figure out. Here, since we already know a little about Merit and the other characters the plotline can be more focused all while giving us more background information on Merit and other characters. 
 In this book we see Merit and Ethan working side-by-side in order to ferret out a threat to the vampires. I think this was cleverly done to get Ethan and Merit time alone and time to find out more about each other which they couldn't have done being around other vampires of Cadogan House. We also a closer view of Merit's family whom we only briefly met in Some Girls Bite. I personally was hoping for a more dramatic exchange between Merit and her father, but I have a feeling that exchange it yet to come. It was kind of nice to see where Merit came from and how different she is from her family. We did get to meet her sister Charlotte, but that makes me wonser more about her brother Robert whom we've had mentioned but hasn't made an appearance. I wonder if there's more to him that we will see in later books? 
 Mallory was interesting in this book. She is obviously still coming into her own powers, couple that with the fact that Merit is still coming into her powers it causes some tension between them. I think this kind of thing is an inevitability with every close friendship, but where Merit and Mallory are concerned it's a little different circumstances. I hope that they can get through this because I really like the realtionship and the back-and-forth that they've got going on. 
 We get to see more of Morgan in this book too. I will be honest I wasn't impresses with the way he got Merit to date him. It's almost as though he were too cowardly to try to woo her the normal way, by hanging out with her on his / her own terms instead of being mandated by a Master vampire. I think that some of his reactions towards Merit were unwarranted. She has a job to do and even though they are dating doesn't mean that she needs to compromise her position so he can feel wanted. With that said though, Merit knew how she felt for him right away, and I think she almost let it go on for too long which is not fair to him either. 
 I look forward to this continuing series. I think that each book just keeps upping the ante on the storyline. This is definitly a series to go back and re-read again and again.
