Nate Romanowski, game warden Joe Pickett's best friend, a "kind of homicidal libertarian folk hero," is off the grid. Although the federal government has been trying to track his whereabouts, they had no luck until Liv Brannon's mother became terminally ill and Liv had to make contact with her. Now they offer Nate a deal...all records will be expunged for both Nate and Liv if Nate will locate and neutralize a perceived threat to national security...one Muhammed Ibraaheem. For six years he was the hardest working journalist in the world. Now he, too, is off the grid. Although sorting out chatter "is like trying to drink from a fire hose," recent intercepted chatter points to a huge upcoming terror event in the Mountain West where no one expects it. A satellite picture shows Ibby engaged in falconry just one hundred miles from Nate. Given Ibby's nationality and a photo taken of him with high-value Al Queda militants in Yemen, the government suspects he is involved with this threat. Nate, as a fellow falconer, is to investigate. Sheridan, Joe Pickett's college age daughter, is caught in this dangerous game, one of many innocent bystanders. As always, this page turner by Mr. Box is an engaging, thought-provoking read.
