I thought it was good!
I understand people being thrown off that the POV changed, but, I mean, it was good! The book did a great job at fleshing out the story.
Book 3 makes the war far more interesting, and whether the QK was redeemed or not doesn't really matter. He is now real and a part of the story, not just some one-dimensional bad guy. Furthermore, his actions and thoughts read like an all-powerful vampire king who has been around for quite some time. Oftentimes, authors tell you some old vampire is ruthless and crazy but they don't make it believable. The redemption arch is a tad bit heavy-handed, but I did not find myself rolling my eyes too much. The QK is old, and he reads like a character who has lived a long time and is just a bit excited to have some action in his life. He is not good nor bad he just is. Even with, again, the redemption being a tad eyebrow arching the QK POV shows some seriously skilled writing chops. Great read.
While not nearly as erotic as the first two (which was heavy on the erotic), I can see these books being one mass volume that is read through all at once in the future. I think, once the series is complete, anyone reading all of the books at once will not find this one out of place.
On a last note, I really enjoyed the book because it was a pallette cleanser from all of the....heavy petting... of the first books. Don't mistake my comments, I did enjoyed the steaminess of the first two books. However, at times, I also found the trouple hotness to be pretty intense. Sometimes, to the detriment of furthering the story. This addition means getting the heat AND a great story when the series eventually gets read all at once.
Excellent writing and a wonderful read.
