This is a classic who done it thriller set in the military and intelligence community. The first chapter does a fantastic job of orienting you within the series and setting up the back-story. You get to know the main character and his back-story and start to care for him and his friends (and possible lover?).
Semi-Spoiler alert: It was rather convenient how, in the story older, more experienced agents from different agencies started to defer to the main character even though he hadn't fully graduated from the training program yet... I don't know how plausible that is, but it did help to keep the story flowing as they followed up less and then worked together and hunted down the bad guys. The ending was very satisfying in how it tied up all loose ends but it did introduce some new plot lines in the last chapter that will be answered in the next book. Overall, a satisfying good read that will keep you engrossed from cover to cover.
