Galactic Patrol
The heart of the foundational space opera series; the Lens is a direct ancestor of the Green Lantern Corps, and the Boskone war shaped all galactic-conflict SF after it.
Book Entry · Science Fiction
Kinnison, now an unattached 'Gray' Lensman answerable to no one, works his way up the Boskonian hierarchy by infiltration, mind-science and the occasional fleet action featuring weapons like the negasphere and the 'sunbeam' — a solar system converted into a vacuum-tube weapon. Smith's escalation reaches a kind of demented grandeur here, while the romance between Kinnison and the red-headed nurse Clarrissa MacDougall (genetic destiny, naturally) gives the saga its human anchor. Serialised in Astounding in 1939 at the height of the magazine's golden age.
Often cited as the series' peak and a defining document of pre-war super-science SF; its arms-race structure echoes through military SF to this day.
Doc Smith's escalating cosmic arms race between Civilisation and Boskone, secretly a two-billion-year war between the Arisians and the Eddorians. The original widescreen space opera.
