Okay, let's start with the most important thing about this book: Is it just me, or does the cover model look like Angelina Jolie?
So the basic plot of Vampire Academy by Richelle Mead is that, in addition to humans, there are three major players in the vampire world. Moroi are mortal vampires who must be protected from the evil immortal vampires, the Strigoi. Moroi are protected by Dhampir who are half vampire and half human (Moroi can't mate with each other). The two main characters are Lissa, a Moroi princess, and her best friend Rose, a Dhampir "guardian"-in-training. The book opens with them being taken back to the secluded Vampire Academy in Montana that they escaped from a year previously. From there, it's half high school cliques and politics and half serious vampire-world issues. For instance, Lissa has secret healing powers that take a toll on her emotionally and physically, and Rose can get inside of Lissa's head to experience what she does. Both girls have complicated romantic interests, and someone is leaving dead animals for Lissa to find.
I enjoyed the book and read it in two sittings. However, I would most likely recommend it to voracious readers who have already read everything else in the library or to readers who really like vampire books. I'd say it's probably comparable to Melissa de la Cruz, possibly a little bit more developed.
