Niki's determination to complete her dead father's unfinished book, his life's work, takes her from India to New York City, where her pursuit of a mysterious immigrant woman turns into an obsession that begins to imperil her daughter, her marriage, and, eventually, Niki herself. When a blizzard blankets NYC, Niki finds herself on a path where the present and past collide violently.

Propulsive and poetic, this elegant literary thriller melds the fervour of Punjab with the frenzy of New York. Spanning the cataclysms of Partition and 9/11, via the brutality of Emergency and the pogrom of 1984, the novel explores the impossible choices women are forced to make in the face of violence, the ties that connect them across ages, and the secrets they store. Interweaving the epic Mahabharata, the poetry of Bulleh Shah, and the legend of Heer, The Radiance of a Thousand Suns is a novel about the mythic and the intimate, about stories on tapestry and mobs that recur, about home and love and history and those heartbreaking moments when they all come crashing together.
