Naomi and Nathan thrive on the yellow journalism of the social-media age. They are nomadic freelancers in pursuit of sensation and depravity. Naomi becomes engrossed about Célestine and Aristide Arosteguy, Marxist philosophers and sexual libertines. Célestine has been found dead and mutilated in her Paris apartment; police suspect Aristide of killing her and consuming parts of her body. Nathan, meanwhile, is in Budapest photographing the controversial work of an unlicensed surgeon. After sleeping with one of Molnár's patients, Nathan contracts a rare STD called Roiphe's. Their parallel narratives become entwined with 3-D printing, North Korea, the Cannes Film Festival and, in an incredible number of varieties, sex.
