There was really only one thing I didn't like about this book, but I'll get to that a little later. 
 I thought the plot of this sequel was awesome. I loved the first book, but this one had more of a mystery and suspenseful thriller feel to it. And I loved how Jessica evolved. I know a lot of people don't like how she was weak in the end, but I feel like the story needed that to drive the rest of it. Because if she wasn't so timid about being Princess, Lucius would have never scolded Claudiu, which wouldn't lead to the death that is an integral part of the story. It shows the sacrifice that comes with the love between Jessica and Lucius as well as showing how each of them rise to strong strengths while the other is week and how they love each other unconditionally. Just because she becomes a ruling princess after the wedding doesn't mean she had to turn the switch that day and go into full power mode. That's unrealistic for an American girl who now rules a vampire kingdom in Romania that she didn't even know about until a year or so before. I think growing into the role of sovereign would be difficult for anybody, especially someone that young. So while it is a story of fantasy, Jessica becoming a dominant ruler is just too much fantasy and is unrealistic even for a fantasy book. And, as I've said before, that weakness in the beginning is what drives the story and allows it to unfold. 
 At first I didn't like how the story went between four people, especially Mindy, because she annoyed the hell out of me in the beginning, but as I got into it, I liked it and I liked how it added to the story. It added a really great element of dramatic irony that intensifies the mystery and suspense. It also shows the reader how all of the characters evolve, good and bad. It adds a human element to it, especially because most of the characters aren't even human anymore. So it makes it more believable and relatable. 
 Now to what I don't like...(view spoiler)[ 
 As I was reading the epilogue, I was waiting for there to be a mention of pregnancy, especially when Jessica remembered what Lucius said when they got married about having like 8 kids or something. But, no baby. Maybe it will be like Twilight and there will be a third baby and Flaviu comes after their baby or something (that can be the ONLY relation to Twilight). I want a baby. Beth Fantaskey needs to give us a baby. 
 Secondly, I don't like how we don't know for sure, 100% that they became king and queen. I know they did, but I would have liked it to just flat out say it. 
 I also wish the story had something more to do with Dorin and Ylenia getting their butts kicked. I know they said they had a trial and destruction, but I despised them so much that it wasn't enough for me. 
 Maybe that can be in the next book. Ylenia rises from the dead to attack the baby. Of course, then I'd have to read about Ylenia more so scratch that idea. (hide spoiler)] 
 So all in all, I was really really happy with this book. If this is the end of our journey with Lucius and Jessica, then I'm happy with how it ended and I think it ended perfectly for them (minus the baby). 
 But I really really want a third book. It seems like every single YA book is part of a trilogy series, so I hope we get a third book. 
 Great read, I recommend it :)
