OK here is a brief intro that might help you understand my review a little bit better. Rosemarie "Rose" Hathaway is a Dhampir, half-human/half-vampire. Vasilisa "Lissa" Dragomir is a Moroi, which is a mortal vampire, and she's the Moroi Princess. Moroi must always be protected from the Strigio: the evil vampires, fast, strong, deadly, and immortal. Strigio are Moroi who drank Moroi blood, which turns them into Strigio. Sometimes Strigio will take Moroi and force them drink from other Moroi. Dhampirs train to be Guardians for the Moroi at St. Vladimir's, which is a school for the Moroi and Dhampirs. The school is hidden from humans deep in the woods of Montana and protected from Strigio by magical wards.
We don't know why, but Lissa and Rose ran away from the Academy. No easy feat. They managed to stay away and avoid threats for 2 years before a dozen Guardians find them and take them back to the school. With the help of one of the Guardians, Dimitri Belikov, Rose is able to stay at the school and resume her training. Before and after school, and every free moment she has to train with Belikov so she'll be ready for the senior field experience. How you do on that test decides who a Guardian will be assigned to. If Rose wants Lissa, a Morio Princess, she has to be on her best behavior and train as much as she can to be ready. The headmistress has made sure Rose and Lissa won't have a lot of time together so they won't leave again, which makes Rose's mission to protect Lissa that much harder. Not to mention they aren't sure who was behind the events that made them leave, but whoever it is has started again. And he/she's closer than they think.
I absolutely loved this book. I love vampires (as some of you have noticed by now). I love them even more when an author comes up with a new kind and Richelle has done it. I can't really explain them in detail without it being confusing so go read the book cause Richelle does better that I could. Makes sense, I mean she did create them.
