To the Commandos, Amazoon is straight out of a delirium-soaked dream. Dense, dripping jungle, a paradise for savage predators-and hell for humans who dare to intrude. The hostile planet hides a deadly treasure they must recover: a cache of stolen Navy materiel. But a crash landing strands the team far off target. And ahead lies a gauntlet of fever and venom, guarded by primordial adversaries deadlier than the most sophisticated star-fighter...crawling, slithering, and swimming machines designed to deliver quick death-or slow torture... "Excellent SF Adventure!"-Andre Norton
