The Radio Man: An Earth Man on Venus (Unabridged‪)‬

When electrical engineer and radio enthusiast Myles Cabot attempts to transport matter via radio wave, he finds himself transported from his home in Boston to the planet Venus, where he is captured by the Formians, a race of antlike creatures. 

After learning of the Cupians, a human-like race that is subservient to the Formians, Cabot escapes and falls in love with the Cupian princess Lilla. Using his in-depth knowledge of Earth science and technology, Cabot leads the oppressed Cupians in a revolt against their Formian masters. 

This 1924 "sword and planet" science fiction novel is sure to be a hit with fans of Edgar Rice Burroughs' John Carter and Mark Twain's A Connecticut Yankee In King Arthur's Court.
