Lover Awakened (Black Dagger Brotherhood, Book 3) by J.R. Ward
Another great book in this series! This book focuses on Zsadist and Bella, but also brings more lore into the story - we learn a bit about sympaths, trainees, etc.
I have to say, the writing and story is getting so much better, too. This book had me riveted, and there were several times I cried! I am just such a fan of this series. I have the next one on it's way to me, and I'm sure I'll be starting it soon :)
