The tainted throne / Alex Rutherford.

"The brutal battle for power continues in the fourth book in the epic Empire of the Moghul series. Agra, India, 1606. Jahangir, the triumphant Moghul Emperor and ruler of most of the Indian subcontinent, is doomed. No amount of wealth and ruthlessness can protect him from his sons' desire for power. The glorious Moghul throne is worth any amount of bloodshed and betrayal; once Jahangir raised troops against his own father; now he faces a bloody battle with Khurram, the ablest of his warring sons. Worse is to come. Just as the heirs of Timur the Great share intelligence, physical strength and utter ruthlessness, they also have a great weakness for wine and opium. Once Jahangir is tempted, his talented wife, Mehrunissa, is only too willing to take up the reins of empire. And with Khurram and his half-brothers each still determined to be their father's heir, the savage battle for the Moghul throne will be more ferocious than even Timur could have imagined. . ."--
