Just before the beautiful empress of Hindustan, Mumtaz Mahal, closed her eyes forever, her husband promised to honour her memory with the most beautiful monument ever built. 'Taj' is the story of this magnificent work and its twenty thousand heroes: architects, calligraphers, master workmen and labourers who, riding on elephants, dragged the enormous blocks of marble. An epic narrative told from the perspective of Balu, a boy from the desert with extraordinary drawing skills who fought against all convention to win back his beloved Aisha, who had been taken into the emperor's harem.
