Among science fiction enthusiasts, among general readers who enjoy a narrative that stirs the imagination, Dr. Edward E. Smnith is gaining an ever-widening circle of followers. He has become the author of interplanetary fiction. Three books have preceded "Skylark Three" - "The Skylark of Space," "Space-hounds of IPC," and "Triplanetary" - and each has been received with greater enthusiasm than its predecessor. "Skylark Three," though a complete story in itself, continues the adventures of Richard Seaton, Marc DuQuesne, Dunark of Kondal and others introduced in "The Skylark of Space." Strange beings on strange worlds are created by the tacile pen and fertile imagination of Dr. Smith. Scientific wonders and adventures merge in a tale that is certain to hold the reader's interest from the very first page. Basically, "Skylark Three" is the story of Dr. Richard Seaton's quest for knowledge with which to combat the vastly superior science of the Fenachrone, a semi-human race of beings from a distant solar system, who threaten the very existence of countless civilized worlds. Somewhere, Seaton believes, must live a cure whose knowledge is greater than that of the invaders.
