A love letter to the cities of the world， from the airline pilot-author of Skyfaring。

Mark Vanhoenacker grew up in his small hometown， spinning the illuminated globe in his bedroom and dreaming of elsewhere - of distant， real cities， and a perfect metropolis that existed only in his imagination。 These places were the source of endless comfort and escape， and of a lasting fascination: streets unspooled， towers shone， and anonymous crowds bustled in cities where Mark could be anyone， perhaps even himself。

Now， as a commercial airline pilot， Mark has spent nearly two decades crossing the skies of our planet， touching down in the cities he imagined as a child。 He experiences our metropolises in short layover visits that repeat over weeks， months or even years， giving him a unique perspective on the urbanization of the world。

In this intimate yet expansive work that weaves travelogue with memoir， Mark celebrates the cities he has come to know and love， through the lens of the hometown his heart has never left。 In chapters that explore emblematic facets of each city's identity - the sweeping roads of Los Angeles， the gates of Jeddah， the intricate， dream-inspired plan of Brasília - he shows us with warmth and fresh eyes the extraordinary places that billions of us call home。
