I believe that I received this book from the author and the Voracious Readers website (sometimes I am not sure who I received the book from because I belong to a few different ARC websites, my bad)
I received an ARC and I am voluntarily leaving an honest review.
If you like a great deal of action, then this is definitely a book for you. This story begins with Rob and the rest of his team arriving in Ukraine. They have been sent as advisors and are to remain hidden so that Russia doesn't find out. They no sooner arrive than they are sent on a mission. They perform well however one of their members is shot by a sniper. This member who is shot is the leader of Rob's group and dies while returning to base. The sniper is one who has been killing high-profile members of the government as well as high-ranking military personnel. Rob decides that given the opportunity, he will avenge his captain's death.
When they arrive back at base that he and Riley are later told that they are being assigned to a special ops group which is more in line with what they normally do. As part of this group, they wind up performing missions, one of which has a major impact on the United States.
To learn what Robb, Riley, and the rest of the group go through, what the missions they perform as well as who and what eventually happens on Rob's hunt for the sniper, then you need to read this book. It is a definite winner.
The only "issue" that I found with the epub copy that I had was that the last three chapters were all right justified with the punctuation that would normally be at the end of the respective sentence was at the first (an easy correction that can be made in editing)
As far as reviews go, I found that this book would be enjoyed by those who enjoy reading fiction that reads like it could have been pulled from the headlines of the paper, combat action literature. I would easily rate this book a solid four stars out of five and would definitely be interested in reading more of this author's books.
As with all my literary ramblings, these opinions are just a few thoughts
