In this Cold War science fiction novel, a team of five specialists undergoes a radical miniaturization process to enter the bloodstream of a dying scientist. Jan Benes, a defector holding critical secrets, suffers an inoperable brain clot that only a microscopic crew can reach from inside. Aboard the submarine Proteus, protagonist Charles Grant and his companions navigate the treacherous landscape of the human circulatory system. They battle white blood cells, survive turbulent heart valves, and navigate the inner ear while racing against a sixty-minute deadline before the shrinking effect expires and they return to full size.
Readers of classic hard science fiction value this work for its mechanical approach to biology and physics. Asimov emphasizes the technical difficulties of miniaturization, such as the logistics of oxygen supply and the physical impact of sound waves on a microscopic scale. Those interested in the intersection of espionage and medicine find a story that treats the human body as a dangerous geographical frontier. The reader gains a visceral understanding of cellular defense mechanisms and the fluid dynamics governing the veins and arteries.
Outward-looking, clear-cut and escapist; an easy read.
Best for readers like The Curious Generalist. Which reader are you?
