Ghost — Alan Lightman

David is a person of modest ambitions who works in a bank, lives in a rooming house, enjoys books and quiet walks by the lake. Three months after unexpectedly being fired from his job, he takes a temporary position at a mortuary. And there, sitting alone in the "slumber room" one afternoon at dusk, he sees something that he cannot comprehend, something that no science can explain, something that will force him to question everything he believes in, including himself. After his metaphysical experience, all his relationships change---with his estranged wife, his girlfriend, his mother--and he grudgingly finds himself at the center of a bitter public controversy over the existence of the supernatural. As David struggles to understand what has happened to him, we embark on a provocative exploration of the delicate divide between the physical world and the spiritual world, between skepticism and faith, between the natural and the supernatural, and between science and religion.
