NHPR and The Music Hall present Writers on a New England Stage with Anthony Doerr, recorded live at The Music Hall in Portsmouth. Doerr's Pulitzer Prize-winning novel All the Light We Cannot See tells the stories of two teenagers swept up in the brutality of World War II. Much has been made of the fact that the book was a ten-year journey for Doerr, but during our conversation, it became clear that that novel was just one facet--and one result--of his free-range inquisitiveness and sense of wonder. Anthony Doerr stood to one corner of the stage with an excitable restlessness, beside a giant screen and a variety of slides, which he used to help tell the story of how his ten-year novel came to be.
