Alexandra Alter and Elizabeth A. Harris write: “This summer, as people across the United States gathered to protest police brutality and racial injustice, Krishan Trotman (right), an executive editor at Hachette Books, approached the head of the company with a proposal. Trotman was worried that the conversation about inequality in the literary world would fade away after the marches died down. So she pitched a new publishing imprint called Legacy Lit, dedicated to social justice and focused on works by writers of color. Michael Pietsch, Hachette’s chief executive, said yes.”
