Air Raid. Number 126 in Series

Don't breathe the air... They are tiny, genetically engineered blue seeds that mature quickly into trees that literally suck all the oxygen out of the air. They're the twisted experiment of the earth-friendly but highly secretive Congress of Concerned Scientists, and now they've been snatched by its head, Dr. Hubert St. Clair. Having killed off all but one of his scientific team, he's leading Remo and Chiun on a chase through the proverbial forest.
He's got enough seeds to choke off the world's oxygen supply, and the ability to create environmental disasters at will. Battling everything from acid rain to blistering heat to frigid cold, the Destroyer races to thwart double disaster in the Amazon rainforest: St. Clair is planting seeds like a maniac and a U. S. President prepares to nuke Brazil into oblivion. Breathlessly action-packed and boasting a winning combination of thrills, humour and mysticism, the Destroyer is one of the bestselling series of all time.
