I wasn't really sure how I would like this book. I think many people felt the same way as me. Dmitri (in the first three Guild Hunter novels) comes across as a very cold and heartless, dark character. He takes pleasure in the pain of others. He doesn't have any qualms about hurting someone who has wronged Raphael or any of his people. He's a difficult character to like. I didn't openly dislike him because ultimately being on Raphael's side is the "good side". I just didn't really think much of him being the hero (for lack of a better term). 
 Also, without Elena and Raphael as the main focus as they were for the first three books I didn't know how it would read. I like books that keep the same couple throughout a series. You get to know them in a way and to change that is a risk. 
 I will admit I was quite surprised. I really liked this book a lot. There were times that I wish it was longer, I didn't want it to end. I think Singh did a wonderful job of creating the relationship between Dmitri and Honor but not having them compromise themselves. They still retain who they were before meeting each other, but they just complement one another. 
 I really like how Singh tied the threads of the past and the present together to create such a comprehensive story of survival and growing / moving on from the past. The past and the present mirrored each other nicely. I don't want to give too much away. I think that the book blurb gives a nice summary of what to expect. 
 I do want to talk about the ending a little. I've read a couple reviews and it seems to be mixed feelings about the ending. I, at this point, don't know exactly how I feel about it myself. I think it was a good ending, I'm completely happy with it. It makes me want to read more books involving these two as the main characters to find out what's going on in their lives. I think it was that I don't feel the ending got the attention it deserved. It's non-chalantly built up throughout the book, but I feel once we get to the end it's just kind of dropped in our laps. We have the story of Honor's retribution on her attackers and the strange tattoo on the dead which take up the bulk of the story. I think if one of these was the main focus without the other then the ending could have been given more time to develop. But, also, this is a first read through. Perhaps on a second read through, knowing what to expect, I will feel differently. It did absolutely nothing to take away from the great addition to the Guild Hunter series. 
 For those wanting Elena and Raphael don't worry they make a few appearances. You can see a little sideline build up of things to come. It's been awhile since I've read the first three books and I think I've forgotten quite a bit about the Angel politics the were taking place. 
 I know there will be a complication book of the short stories Singh has released in anthologies in the Guild Hunter world coming out in late February '12 (?). Then I believe the 5th book out sometime in 2012. Many people speculate that she will choose another of the seven to headline the next book. If that it true Singh makes no hints about who the next one would be in this book. I guess we will have to just wait and see. Until Then!
