Books about Shanghai

Aaron asked me to recommend books about Shanghai. While there are many excellent books on many other famous cities in the world, such as Paris and Rome, good books about Shanghai for general interests are rare. Please feel free to grab any of those tour books on Shanghai. For in-depth readings, I highly recommend Shanghai Modern (by Leo Lee). It gives a fascinating introduction to Shanghai's history as a semi-colonial city and how the city became a converging point for various political and cultural conflicts.
