Fresh from stopping a terrorist hijacking, veteran covert operator John Clark is tapped to build and lead a secret multinational counterterrorism unit: Rainbow, headquartered in England and staffed with the best special-operations soldiers and intelligence officers the Western allies can offer. Almost as soon as it stands up, Rainbow is thrown into a rapid series of crises — a bank robbery turned hostage siege, a kidnapping, an assault on an amusement park — each one handled with the precision Clancy renders in exacting tactical detail.
But the incidents aren't random. As Clark, his son-in-law Ding Chavez, and the Rainbow team trace the pattern, they uncover a far more chilling design: a cabal of eco-extremists who believe humanity itself is the disease, and who are quietly assembling the means to "cure" the planet by unleashing a plague that could wipe out most of the human race.
Sweeping, meticulously researched, and relentlessly paced, Rainbow Six is a landmark techno-thriller that pits an elite team against a doomsday conspiracy — and lent its name to one of gaming's most enduring franchises.
