In Parenthesis is one of the greatest works to emerge from the First World War. 'The holy book of twentieth-century visionary modernism. Ancient and brand-new, In Parenthesis is this island's book of all books, an incomparable and ever-intensifying masterpiece. It is radical, beautiful, humane and mysterious. It is a book about war that has the power to defeat death. It is a living breathing mythic miracle of a book.' Max Porter
