Nat Phillips leads an elite roster of military mercenaries. They are ex-Special Forces, combat divers, medics, communications specialists, and intelligence officers. They are decorated veterans of the U.S. military and experts in international warfare. And now they must hone their skills domestically.           Under a new partnership between billionaire tech innovator/military contractor Tristan Dent and the U.S. government, Nat and his team are given a new identity: a lawful in-extremis operations network. And a new code-name: “Rockets Red Glare.”           These U.S.-based operators are assigned to maximize the existing paramilitary and law enforcement organizations within the United States during times of national crisis. They’re in training and on stand-by—until a terrorist brutally murders a presidential candidate at his summer headquarters on the island of Nantucket.   Suddenly, the plan is no longer the stuff of Mission: Impossible. Emergency operations happening not overseas but right here in the U.S. This is real.
