Another good Brin book. "Practice makes perfect" brings a whole new meaning when the physics have gone a bit strange. In this, people make simple clothes out of rags and junk, and give them to others to wear and use for a while. Later, those practiced items are taken back once they are high enough quality. The upperclass has even more of a reason to make the lowerclass do all the work.

Not my favorite Brin, but fun concept.

a unique story about travel to a strange world where the laws of physics are different. Science is a mix of modern and stoneage and used items get better no worse with time.
