Are the self-programming robots on the moon ensuring “peace on Earth,” or are they secretly plotting a terrestrial invasion of their own? Only Ijon Tichy, sent on a dangerous mission to report on the robots’ activities, knows for sure. But, as luck would have it, he is caught by a highly focused ray, which severs his corpus collosum and leaves the left side of his brain at odds with the right. Has he returned to Earth with the secret that could save all humanity? His left brain can’t remember, and his right brain can’t tell. Agents from the East and the West race to get to Tichy’s forgotten but priceless information first; Tichy, whose left hand keeps punching him and pinching ladies’ bottoms, struggles for control of the lost memory and of his own two warring sides. “[A] funny satirical novel about over-saving the world.” “Has more ideas in fewer pages than anybody else could manage.

He was born in Lvov, Poland, and lives in Krakow
