The first time that Melanie met Clara, Melanie was stunned by Clara's sense of authority, and Clara was struck by Melanie's pink, glittery nails, which shimmered in the dark. She looks like a child, thought the first. She looks like a doll, pondered the second.

These two women, both of the same generation and exposed to the same media throughout their lives, could not be more different in adulthood. Melanie is a social media superstar, broadcasting her children's daily lives on a family YouTube channel. Clara is a young police officer, assigned to the case after Melanie's daughter Kimmy is abducted.

Traversing the Big Brother generation, the social media influencer generation, and right up to the 2030s, Delphine de Vigan offers a bone-chilling expose of a world where everything is broadcasted and profited from, even family happiness.
