Upon the twentieth anniversary of its publication in the UK, Chris Cox has a piece in The Guardian discussing the impact of William Styron’s memoir about depression, Darkness Visible.  As Cox notes,”Darkness Visible has become the founding text of what is now a flourishing genre known as depression memoir. You can feel its reassuring hand on the shoulder of many brave and searching accounts, including Andrew Solomon’s The Noonday Demon, Lewis Wolpert’s Malignant Sadness, and Tim Lott’s The Scent of Dried Roses.”
