I love the Dark Hunter series. That being said, I wanted to like this one more than I did. At some points, I really considered giving it 5 stars.
A lot happened in this story and I loved seeing another side of Valerius. Of course, if you've been paying attention, none of it seems all that surprising. Even the BIG moment in the book (non-romantic plot) wasn't too much of a shock (that is, if you've been reading CoN). That being said, I feel the same about it as the other Kenyon books I've read.
I enjoy them while I'm reading them, I intend to read all the others. When I'm in the moment the story is all I care about. However, I'll have no trouble waiting a while until I read the next.
