John Delaney, a seasoned sailor aboard the USS Ronald Reagan, faces one of the greatest challenges of his career when the ship is thrust into a deadly global conflict in the Pacific. With Lieutenant Commander Danielle "Spooky" Lawson and his close friend, Lieutenant Commander Cameron "Gazer" Mitchell, at his side, Delaney must navigate the chaos of modern warfare. The Reagan becomes the prime target of relentless missile strikes and cyber warfare, as powerful enemies seek to cripple the U.S. Navy. But while the battle rages on the open seas, Delaney is also fighting a more personal war. Haunted by the recent loss of Gazer, his close friend and crewmate, Delaney struggles to maintain his focus under the weight of grief. The mental toll of war is heavy, and Delaney's internal battle is as fierce as the external threats surrounding the Reagan.
