A stunning new novel about an ordinary man's encounter with the extraordinary, from the author of Einstein's Dreams.David Kurzweil, a quiet man with modest ambitions, was taking a break at his new job, when he saw something out of the corner of his eye. Something no science could explain. Suddenly David's life is changed, and he soon finds himself in the middle of a wild public controversy over the existence of the supernatural. As David searches for an explanation, we embark on a provocative exploration of the delicate divide between the physical and the spiritual, between science and religion as only Alan Lightman could provide. Combining a beautiful narrative with provocative ideas, Ghost investigates timeless questions that continue to challenge the truth as we know it.
