In For Honor, a chilling new thriller in the New York Times bestselling Tom Clancy's Op-Center series, simmering tensions threaten to ignite when a silo of Cold War missiles surfaces in the Middle East. In 1962, at the height of the Cold War, the Soviet Union sent a convoy of nuclear missiles to Cuba. The crisis that followed almost triggered World War III. However, while all eyes were on the Caribbean, not all of the missiles were sent to Cuba. Several ships slipped from the flotilla and headed for a fishing village in a remote, frigid, northeastern Soviet frontier. There, a silo was constructed not far from Alaska. More than sixty years later, that silo and its lethal contents are intact. Now, Iranian scientists team with a Russian agent and his estranged, arms-smuggling father to bring those missiles to Tehran. When an intel officer at Op Center starts picking up hints of the deal, the government’s off-the-grid unit must track the unknown actors – and try to decide whether they can count on data provided by an Iranian defector, a man who has more at stake than anyone realizes. At the same time, Op-Center sends a lone agent to Havana to try and find an aging revolutionary, a woman, who may hold the key to pinpointing the location of the silo. Complicating matters is a turf war between Op Center, the White House, and the FBI that threatens to compromise the investigation...as the time to act grows perilously short.

After an intelligence failure at Op-Center results in a major terrorist attack, director Chase Williams radically transforms the agency into a ground-breaking mobile strike force. It’s a beautiful day in Manhattan as excited tourists board the floating Air & Space Museum on the USS Intrepid—until a horrible explosion rips across the flight deck, showering the body parts of innocent people everywhere. The perpetrator is none other than Captain Ahmed Salehi, an Iranian mastermind whose last terrorism plot was foiled at the last minute by Op-Center. Back in Washington, the White House orders Op-Center disbanded—or so it seems. Unbeknownst to America’s enemies, director Chase Williams has been put in charge of a brand-new, top-secret covert attack team known only as BLACK WASP. Its members, each chosen for their unique set of specialized black-ops skills—martial arts expert Lieutenant Grace Lee, sharpshooter Lance Corporal Jaz Rivette, and JAG attorney and criminologist Major Hamilton Breen—have been assigned to seek out Salehi and finally bring him to justice. But Salehi is part of an even more frightening conspiracy, led by a renegade Iranian tycoon determined to establish a new Islamic State that will dwarf the horrors of ISIS. From the heart of Manhattan, to the swamps of Trinidad, to the sunbaked mud villages of Yemen, this new Op-Center is America’s only line of defense against a bloody Middle Eastern tyrant.
