Marie Darrieussecq is one of the leading voices in contemporary French literature. Her first novel, Pig Tales, was a finalist for France's prestigious Prix Goncourt in 1996 and became an international bestseller. Her 2013 novel Men: A Novel of Cinema and Desire received the Prix Médicis, and her luminous, voluptuous portrait of the artist Paula Modersohn-Becker, Being Here Is Everything, was published in English by Semiotext(e) in 2017. Darrieussecq has also worked as a translator and a psychoanalyst.

Plagued by insomnia for twenty years, Marie Darrieussecq turns her attention to the causes, implications, and consequences of sleeplessness: a nocturnal suffering that culminates at four AM and then defines the next day. Prevented from falling asleep by her dread of exhaustion the next day, Darrieussecq turns to hypnosis, psychoanalysis, alcohol, pills, and meditation. Her entrapment within this spiraling anguish prompts her inspired, ingenious search across literature, geopolitical history, psychoanalysis, and her own experience to better understand where insomnia comes from and what it might mean.
