The book that inspired the Star Trek franchise! With the exception of the works of H. G. Wells and Jules Verne, 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. The seminal space opera.

Isaac Asimov wrote that "It had adventure of an unprecedented kind...the first great classic of American science fiction”. A fast, lean plot, an air of excitement. Four characters who are comfortingly bigger than life and the feeling that adventures are waiting everywhere!
