In this travelogue, Theroux retraces the epic journey he took thirty years earlier in his classic The Great Railway Bazaar . He travels through Eastern Europe, Central Asia, India, and Southeast Asia, reflecting on how the world—and he himself—has changed over three decades.
Contrast the restless energy of the young traveler in The Great Railway Bazaar with the more reflective, often cynical, observations of the older Theroux.
