Stylish and camera-obsessed, Naomi and Nathan are lovers and competitors - nomadic freelancers in pursuit of sensation and depravity in the social media age, encountering each other only in airport hotels and browser windows. Naomi finds herself drawn to the headlines surrounding Celestine and Aristide Arosteguy, Marxist philosophers and sexual libertines. Celestine has been found dead and mutilated in her Paris apartment. Aristide, suspected of the killing, has disappeared. Naomi sets off in pursuit, but the secrets she discovers are as seductive as they are disturbing.
