Vencel had known the mountain when he was a boy. He had climbed it, hunter on it, fished in its streams. But when he cane back, he found the mountain a place of swiftly spilling blood and sudden death. Vencel turned into an angry, vengeful man, and he swore to flush out the terrifying menace of Blue Peak. But no man alone could fight the barbarous enemy hidden deep inside the mountain. So Vencel joined the team of army brass, FBI agents, and the nation's top scientists. All of them caught up in a desperate hunt for the most devastating weapon ever devised for the destruction of mankind.....
