Thirty years ago Paul Theroux left London and travelled across Asia and back again by train. His account of the journey - "The Great Railway Bazaar" - was a landmark book and made his name as the foremost travel writer of his generation. Now Theroux makes the trip all over again. Through Eastern Europe, India and Asia to discover the changes that have swept the continents, and also to learn what an old man will make of a young man's journey. "Ghost Train to the Eastern Star" is a brilliant chronicle of change and an exploration of how travel is 'the saddest of pleasures'.
