Do not expect the technological accuracy of hard science fiction or the social commentary of soft SF; this is Space Opera, adventure on a grand scale. In Skylark, the men are real men, the women are real women, and small furry creatures from Alpha Centauri just do not stand a chance.
E.E. "Doc" Smith is hailed as being the creator of both interstellar science fiction and of the Space Opera sub-genre. His visions of epic space battles by the greatest of heroes against the evilest of villains inspired many great SF writers through the 20th century, eventually leading to its eminent descendant Star Wars. This is were it all began, boldly going to galaxies far far away, seeking out new worlds and ways of writing SF. Skylark's faults may be many, but they are forgivable. If later works seem more refined, it is because this is the mother lode. Forget characterisation and realism: just hold on tight and enjoy the ride. All aboard?
