In 2012, Jerry Pinto published his debut novel, Em and the Big Hoom, which drew upon his experience of living with a mother who was bipolar. It touched thousands of readers, among them many who had similar experiences-of living with someone with a mental illness or infirmity. Some of these readers shared their stories with him, and agreed to share them with the world. A Book of Light collects these harrowing yet moving, even empowering, stories-about the terror and majesty of love; the bleakness and unexpected grace of life; the fragility and immense strength of the human mind.
