User: What are the five best Kim Stanley Robinson novels?
Assistant: 1) Aurora - a unique and depressing take on interstellar colonization.
2) The Years of Rice and Salt - the Iroquois team up with a samurai warrior in the 17th Century.
3) Red Mars -  the descriptions of life in the early days of Martian colonization are fascinating.  
4) 2312 - after reading this book, you will want to live inside an asteroid.  Somehow, Kim Stanley Robinson turned space into 1970s Berkley, CA.
5) The Ministry for the Future - a scary but very hopeful book about global warming.
