Scott Bradley James arrives in Annapolis, Maryland, as a plebe in the class of 1941 without a terribly good idea why he wants to be a naval officer, other than that his father was a sailor, and he wants to see the world, whatever that means. Scott and his roommate become fast friends, and, after surviving scrapes of their own making, the two fetch up at Pearl Harbor. War is brewing, and their class has graduated early. They have been sent to battle stations. Admiral James Stavridis is an acclaimed novelist, a decorated military leader and a great student of military history. He draws on it all to capture the experience of being storm-tossed by the bloody first years of the Second World War. Scott Bradley James is a talented young officer, but he has a lot to learn. And war will have a lot to teach him.

It is 20 years after the catastrophic war between the United States and China that brought down the old American political order. A new party has emerged in the US, and efforts to cement its grip have resulted in mounting violent resistance. The American president has control of the media, but he is beginning to lose control of the streets. Many fear he’ll stop at nothing to remain in the White House. Suddenly, he collapses in the middle of an address to the nation. After an initial flurry of misinformation, the administration reluctantly announces his death. A cover-up ensues, conspiracy theories abound, and the country descends into a new type of civil war. All signs point to a profound breakthrough in AI, of which the remote assassination of an American president is hardly the most game-changing ramification.

On March 12, 2034, US Navy Commodore Sarah Hunt is on the bridge of her flagship, the guided missile destroyer USS John Paul Jones, conducting a routine freedom of navigation patrol in the South China Sea when her ship detects an unflagged trawler in clear distress, smoke billowing from its bridge. On that same day, US Marine aviator Major Chris "Wedge" Mitchell is flying an F35E Lightning over the Strait of Hormuz, testing a new stealth technology as he flirts with Iranian airspace. By the end of that day, Wedge will be an Iranian prisoner, and Sarah Hunt's destroyer will lie at the bottom of the sea, sunk by the Chinese Navy. In a single day, America's faith in its military's strategic pre-eminence is in tatters. A new, terrifying era is at hand.
