Gabrielle Levy's The Insomniac Society is the international phenomenon for those having sleepless nights everywhere . . .

Five people. One thing in common: none of them can sleep.

Claire, who sits awake beside a snoring husband and a little boy who is not hers.

Jacques, a psychiatrist at the end of his career whose lonely nights are punctuated only by anonymous phone calls.

Michèle, a retiree whose dark secret compels her out of bed and to church.

Lena, a young goth who cannot brave the dawn, volunteering at a local café.

Hervé, a shy accountant who sits in bed, panicking about his job while scrolling through emails into the early hours.

As meetings led by sleep specialist Marie-Hélène draw them together, friendships will be formed and confessions made... but will they discover what’s keeping them awake? And more importantly: will they be able to get to sleep?
