Bernardine Evaristo’s Manifesto — part instructional guide for artists, part call to arms for equality, part literary memoir —shimmers with unfailing self-belief and a strong vein of humility. When Evaristo won the Booker Prize in 2019 for her magnificent seventh novel Girl, Woman, Other,the first black woman to do so, it was the pinnacle of a career devoted not just to honing her craft but to helping others traditionally excluded from the literary world, through teaching, mentoring and activism.
