It was Cobb Anderson who built the "boppers"-the first robots with real
brains. Now, in 2020, Cobb is just another aged "pheezer" with a bad
heart, drinking and grooving on the old tunes in Florida retirement
hell. His "bops" have come a long way, though, rebelling against their
subjugation to set up their own society on the moon. And now they're
offering creator Cobb immortality but at a stiff price: his body his
soul...and his world.
