"I don’t believe in God, but I miss him." So begins Julian Barnes’s brilliant new book that is, among many things, a family memoir, an exchange with his brother (a philosopher), a meditation on mortality and the fear of death, a celebration of art, an argument with and about God, and a homage to the writer Jules Renard. Barnes also draws poignant portraits of the last days of his parents, recalled with great detail, affection and exasperation. Other examples he takes up include writers, "most of them dead and quite a few of them French," as well as some composers, for good measure.
