Tom Swift and His Big Tunnel; Or, The Hidden City of the Andes

In his cluttered lab, young inventor Tom Swift wrestles with a perplexing problem when a thunderous knock shakes the door. The visitor is Koku, a gentle giant whose strength often saves Tom from the limits of his machinery, and who reluctantly reports a mysterious man waiting at the gate.

Intrigued by the prospect of new discoveries and the challenge to his engineering skill, Tom gathers his team and prepares his latest inventions for the massive excavation. As the project looms, he must balance the demands of his business, the loyalty of his unusual helpers, and the ever‑present risk of rivals trying to steal his ideas. Listeners will be drawn into the early stages of this high‑stakes adventure, where ingenuity meets danger.
