Cities investigates the following intriguing questions: why did cities start to occur around 6,000 years ago, how have they evolved, why do so many of us choose to live in them, how do they affect us, and what does the future hold at a time when we're increasingly connected by technology? 

In Cities, Monica L. Smith points out that, even if you don't live in a city, your life is inevitably affected by one, whether you commute into one for work, sell coffee beans to a company that supplies urban coffee shops, or host city-dwelling tourists seeking adventure and respite from the city in your remote village.
