1659. Mughal India. The imperial court, a place of opulence and excess; music, drugs, eunuchs and harems. Two brothers, whose mother's death inspired the Taj Mahal, are heirs to this Muslim empire. Now they fight ferociously for succession. Dara, the crown prince, has the love of the people - and of his emperor father - but younger brother Aurangzeb holds a different vision for India's future. Islam inspires poetry in Dara, puritanical rigour in Aurangzeb. Can Jahanara, their beloved sister, assuage Aurangzeb's resolve to seize the Peacock Throne and purge the empire? There is no limit to what families do to one another, so much crueller than they are to strangers.
