The Skylark of Space (Skylark #1)

Finding that his government laboratory coworkers do not believe his discovery of a revolutionary power source that will enable interstellar flight, Dr. Richard Seaton acquires rights to his discovery from the government and commercializes it with the aid of his friend, millionaire inventor Martin Crane. When a former colleague tries to steal the invention, not only the future of Dr. Seaton and his allies, but ultimately the entire world hangs in the balance!

The first of the great "space opera" science fiction novels, The Skylark of Space remains a thrilling tale more than 80 years after its creation.

"With the exception of the works of H. G. Wells, possibly those of Jules Verne -- and almost no other writer -- it has inspired more imitators and done more to change the nature of all the science fiction written after it than almost any other single work." -- Frederik Pohl
