Sons of valor ... Navy SEAL Keith ''Chunk'' Redman has been one of the military's top doorkickers since the day he pinned on his trident: loyal, single-minded, lethal. Tasked to lead a new, covert team of Tier One SEALs—the most elite special operators in the world—Chunk can no longer simply rely on the status quo. To safeguard America, he needs help to stay a step ahead of its adversaries. Brilliant at spotting patterns in the data that others miss, ex-CIA analyst Whitney Watts sees evidence of a troubling link between illicit Chinese arms sales and an attack on a US military convoy in Afghanistan. If she's right, it would portend not only massive casualties, but a devastating threat to global stability. Sons of war ... From the ashes of a never-ending war, a new generation of terrorists has arisen: sophisticated, tech-savvy, and hiding in plain sight among America's allies. Battered by the Taliban and by the West, they call themselves al Qadr—Power and Destiny—and they're determined to wrest back control of their homeland. Armed with a powerful combat drone, they can strike with deadly precision at US forces in the region—but their ambitions reach far, far beyond that. A new legacy ... The new Tier One's first mission will require them to not only prove themselves, but to stop an enemy who's using military tactics against them. Chunk and his team aren't just the tip of the spear; they're America's first, last, and best counterterrorism defense. And they couldn't have arrived at a more urgent—and perilous—time.

They train to be the toughest, the smartest, the most covert operators in the world—they are the Tier One Navy SEALs, led by Lieutenant Commander Keith Chunk Redman. When a former teammate of Chunk's is killed in a shocking ambush, rumors begin to fly that the Lion of Ramadi, the infamous Iraq War sniper who racked up dozens of American kills, has returned with a mission to target American SEALs. Chunk and his core team—Saw, a skilled and lethal sniper; Riker, who has an uncanny ability to escape death; and Whitney Watts, a former CIA analyst who sees patterns everyone else seems to miss—are mobilized to prosecute the threat. But this is no ordinary counterattack, because someone posts the details of the hit all over social media, taunting the American SEALs. Worse, the enemy seems prepared to counter all the Tier One's moves, a dangerous new stage in the war on terror and a troubling sign that whoever is behind the attack is planning something bigger. Fearing they may have been duped into chasing the wrong target, Chunk and his team embark on a high-stakes cat-and-mouse mission where nothing—and no one—is what they expect. And when their enemy finds a way to strike at the heart of what's nearest and dearest to them, it will test not only their bonds but also the personal sacrifices they've made to keep America safe.

In Sons of Valor III: War Machine, Chunk and Whitney are forced into a deadly match of wits with a terrorist mastermind and a terrifying weapon unlike anything they've ever encountered. After a shootout in Dubai left Hamza al Saud dead and elevated brilliant aeronautical engineer Qasim Nadar to hero status in England, everyone assumes the terrorist threat from al Qadar has been eliminated. Everyone except JSOC counter-terrorism analyst Whitney Watts. But when she decides to help MI6 penetrate Nadar's secret network, Watts she gets a little too close to the truth and finds herself in a deadly situation not even her teammates from Tier One can save her from. As Lieutenant Commander Keith "Chunk" Redman and the rest of Tier One fan out across London in search of Watts, Nadar prepares to unleash his most dangerous weapon yet—an advanced drone with artificial intelligence and stealth technology. To stop a horrifying attack on London, Chunk and his Navy SEAL brethren must seek help from an unexpected ally and find a way to stop a war machine that was designed to be unstoppable.
