Frostbite (Vampire Academy, Book 2) by Richelle Mead
After reading the first in this series (Vampire Academy), I went out and bought the next one! I think this one is even better - and that's saying a lot! I love this series, and can't wait until the next book comes out (come on November!!).
In this book, Rose comes closer to graduation, while outside the academy, the Strogoi has upped the ante in their attacks against Moroi and the guardians.
There were many parts of this book which brought tears to my eyes, both happy and sad ones. I love books that really pull at my emotions, and this one definitely did that.
Highly recommend this series!
