In a romantic and stirring account, Michel Peissel describes his experiences exploring one of the most rugged and least known regions of the world - a true lost horizon in the Himalayas. On the very roof of the world lies the small inaccessible land of Mustang, or Lo, as it is known to the few who have heard of it. Its people, the Lobas, of Tibetan stock, do not use the wheel...they still believe that the earth is flat...yet the enjoy a highly developed civilization with great castles, fortified towns and large monasteries, teeming with the mysterious life of an unspoiled, rich, mediaeval society.
