Iran in 1576 is a place of peace, wealth, and dazzling beauty. But when the Shah dies without having named an heir, the court is thrown into tumult. Princess Pari, the Shah's daughter and closest adviser, knows more about the inner workings of the state than almost anyone, but the princess's maneuvers to instill order after her father's sudden death incite resentment and dissent. Pari and her trusted servant, a eunuch able to navigate the harem as well as the world beyond the palace walls, are in possession of an incredible tapestry of secrets and information that reveals a power struggle of epic proportions.

Based loosely on the life of Princess Pari Khan Khanoom, Equal of the Sun is a riveting story of political intrigue and a moving portrait of an unlikely friendship between a princess and a eunuch. This rich and labyrinthine world includes a stunning cast of characters, passionate and brave men and women who defy or embrace their destiny in a Machiavellian game played by those who lust for power and will do anything to attain it.
