The pay cable network will pay "low seven-figures for the book and the author will be executive producer of what HBO will develop as a limited series," reports Deadline. The Vanishing Half, which is currently on The New York Times' bestseller list, "focuses on the Vignes sisters, identical twins who, after growing up together in a small, southern black community, run away at age sixteen," per Deadline. "It’s not just the shape of their daily lives that is different as adults, it’s everything: their families, their communities, their racial identities. Ten years later, one sister lives with her black daughter in the same southern town she once tried to escape. The other passes for white, hiding her identity from her husband, who knows nothing of her past. Even separated by so many miles and just as many lies, the fates of the twins remain intertwined. What will happen to the next generation, when their own daughters’ storylines intersect?"
