A witty sharply observed journey down the length of North and South America.

Beginning his journey in Boston, where he boarded the subway commuter train, and catching trains of all kinds on the way, Paul Theroux tells of his voyage from ice-bound Massachusetts and Illinois to the arid plateau of Argentina's most southerly tip. Sweating and shivering by turns as the temperature and altitude shoot up and down, thrown in with the appalling Mr Thornberry in Limón and reading nightly to the blind writer, Borges, in Buenos Aires, Theroux vividly evokes the contrasts of a journey 'to the end of the line'.
