Tom Swift and his Triphibian Atomicar

An atomic-powered car that travels on land, water, and through the air -- Tom Swift Jr.'s latest invention -- is an extraordinary achievement. But even its young inventor could not anticipate what a dramatic role the Triphibian Atomicar would play in a technical aid mission which takes Tom and his top-flight engineers to the untamed Asian land of Kabulistan, to help the new republic develop its natural resources.

Time and again Tom must pit his skill and courage against fierce, nomadic tribesmen. But this is not a one-sided conflict between the ancient and the modern. Beneath the façade of thunderous hoofbeats, spears, and scimitars is a scientific mastermind bent on destroying the members of the Swift expedition in order to conceal from the Kabulistan government his discovery of a fabulous ruby mine lost for two centuries.

After a series of danger-packed episodes, Tom and his pal Bud Barclay are caught in a seemingly inextricable, underground trap. How Tom builds a "do-it-yourself" rocket in a cavern laboratory and sends it homing for aid is a brilliant stroke of ingenuity.

The young scientist-inventor's daring exploits in the primitive Middle East country of Kabulistan will keep the reader breathless with suspense until the last page of this gripping story.
