This is a very useful and well written book. Managing a city is quite a task and, honeslty, some details can easily escape your attention. The guidelines and tips that this book gives are mostly easy and quick to implement so I'm finding myself consulting it to improve my own city designs. I advice to give this book a good read, even if you are using a real city for your chronicles.
Last but not least, the fictional city that the book includes in chapter six is pretty well done, so if you want to save yourself a lot of work you can use it.
