有声读物: First Lensman

The Secret Planet. No human had ever landed on the hidden planet of Arisia. A mysterious space barrier turned back both men and ships. Then the word came to Earth, "Go to Arisia!", Virgil Samms of the Galactic Patrol went--and came back with the Lens, the strange device that gave its wearer powers no man had ever possessed before. Samms knew the price of that power would be high. But even he had no idea of the ultimate cost, and the weird destiny waiting for the First Lensman. First Lensman is the sequel to Triplanetary, and the second book of E.E. "Doc" Smith's classic Lensman series. (from the original book cover and Mark Nelson)
