"The First Commandment" by Brad Thor

New York Times Bestselling author Brad Thor mentioned Valhalla Training Center in a book last year and it started a great relationship... In his latest Thriller we take on a significant part of the action as his hero, Scott Harvath, continues to win his war on terror with a little help from Valhalla! "Publisher's Weekly says: Bestseller Thor's latest thrill-ride begins in anguish. Scot Harvath, navy SEAL turned Homeland Security superagent, sits at the bedside of girlfriend Tracy Hastings, who's in a deep coma after being gravely wounded at the end of Takedown. Meanwhile, five terrorists have been released from Guantánamo Bay as part of a secret hostage deal forced upon U.S. president Jack Rutledge. When one of the terrorists starts targeting Scot's friends and family, Scot discovers that the president won't allow the assassin to be hunted down. Soon enough, Scot is on the run from his own government and in pursuit of the killer. Many characters make appearances from earlier books, in particular Scot's ongoing nemesis, the fascinating, intelligence-gathering expert known as the Troll. It's a long, violent, shoot-'em-up, blow-'em-up pulse-pounder that will leave Thor's fans cheering and begging for more."
