Vergil Ulam, brilliant, unorthodox, has exceeded every ethical guideline for genetic research to engineer blood cells that think for themselves. When his illegal experiments are discovered, he makes a desperate attempt to save his work - by injecting himself with his own creation.
He's infected. What he carries is contagious. Deadly.
Moving from the smallest blocks of matter to forces that could transform the universe, Greg Bear's Blood Music is dazzling, apocalyptic, utterly engrossing - a timeless SF classic.
