E.E. 'Doc’ Smith 
Subspace Explorers [EPUB ebook] 

All the creative energies of the West have been directed into space exploration and development – dozens of new worlds are being opened up. Left behind on Earth are the sluggish remnants of former greatness. But in the East, a mighty dictatorship has arisen – a single absolute monarch rules: The Nameless One of the East. What follows is a raging conflict, on Earth and in space – conflict as only master pulp storyteller E.E. "Doc" Smith can write it.
