In Alan Lightman's new book, a verse narrative, we meet a man who has lost his faith in all things following a mysterious personal tragedy. After decades of living "hung like a dried fly," emptied and haunted by his past, the narrator awakens one morning revitalized and begins a Dante-like journey to find something to believe in, first turning to the world of science and then to the world of philosophy, religion, and human life. As his personal story is slowly revealed, little by little, we confront the great questions of the cosmos and of the human heart, some questions with answers and others without.
