Speakers at the Penzance Literary Festival (July 3-6) will include Horatio Clare, who will be discussing his “love-hate relationship” with borders with Philip Marsden, whose new book, The Summer Isles: A Sea Voyage, is due to be published by Granta in October. Clare will also be reading from Something of His Art, about his walk in the footsteps of JS Bach, his readings interspersed with music by other composers played on period instruments by the Heinichen Ensemble.

  Also on the bill are Nicholas Jubber, whose latest book, Epic Continent, is inspired by poems — from The Odyssey to the Kosovo Cycle — telling the story of Europe; Philip Hoare, author most recently of RisingTideFallingStar, about his obsession with the sea; and Anna Pincus, founder and co-editor of Refugee Tales, who will be discussing with the novelist Patrick Gale, a contributor to her latest volume, the project she began to tell the stories of people trapped in indefinite detention.
