The President of the Galactic Federation was dying of a "silent clot"—a blockage so deep in the cerebral cortex that no external laser could reach it. Thorne’s job was to enter the "Living River" and dismantle the obstruction from within.

True to his background as a biochemist, Asimov shines when explaining the chemical processes within the blood. He dedicates significant attention to hemoglobin, the iron-based protein that binds oxygen. He explains how slight changes in acidity and temperature dictate whether hemoglobin holds onto oxygen or releases it to starving tissues. 4. Defense and Repair El Rio Viviente Isaac Asimov Pdf
