"Tom, that strange gas is fantastic--disintegrates everything it touches! What do you think it is?"

Fascinated by the amazing report from a pilot who crash-landed in the African jungle, Tom Swift Jr.'s eyes glow with curiosity as he replies: "Sounds like antiprotons rampaging. Such a phenomenon is unknown on earth. This may be the greatest discovery of the century. It could revolutionize the whole science of atomic energy. Let's investigate that taboo mountain."

Although several of the young inventor's associates view his latest expedition with skepticism, Tom sets off in the Flying Lab for the Dark Continent to fathom the secret of the mysterious mountain. The deadly vapors which have terrified the natives for generations challenge even the scientific genius of Tom and his companions.

When their atomic drill inexplicably is sucked into a forbidding peak. A series of startling events threaten the Swift expedition. How Tom, with his new invention the Terrasphere, conquers a heretofore unknown, violent quirk of nature brings this breath-taking story to a spectacular finish.
