    Emma Averell has everything under control - successful lawyer on track to make partner, mother to two children, wife to stay-at-home dad Robert. But as her fortieth birthday approaches, a terrifying possibility haunts her: will she follow in her mother's footsteps? Years ago, her mother had a psychotic break on her fortieth birthday, attempting to smother Emma's sister Phoebe before being institutionalized for life. The countdown begins twelve days before Emma's birthday when she wakes at precisely 1:13 a.m., convinced someone is in the house. Though she finds nothing amiss, this becomes the first of many sleepless nights. Each passing day brings mounting exhaustion as Emma's grip on reality weakens. She finds herself compulsively checking doors and windows, staring into dark cupboards, and reciting a mysterious sequence of numbers: "1 5 5 2 1 8 2 2 2 1 1 3." What would you do if your mind began betraying you? If the very thing you feared most - inheriting your mother's madness - seemed to be coming true? For Emma, the ticking clock becomes deafening as strange incidents multiply and her carefully constructed life begins to unravel.
