This was the most emotional out of the series I thought. Each book is dark and gritty, but this one dealt with some subjects I distant comfortable with. I loved the connection between Zoya and Valentin, even in sleep he protects her, "I could not move from my side of the makeshift bed. Valentin’s arm was wrapped around my waist. Even in sleep, he wasn’t letting me go." I enjoyed this book, it was emotional and gritty.
