Nightmares still haunt Chloe thirteen years after a fatal tragedy led to the disintegration of her family. Her mother, Jules, has a busy tech career, a long history of chronic pain—and little time for Chloe. After Chloe drops out of university to travel for a year, Jules’s OxyContin dependency quickly worsens. Aftershock follows their parallel journeys: Jules struggles to regain control of her life, while Chloe, after a rocky visit with her estranged father in New Zealand, resolves to go off the map and spend some time alone, travelling. When Jules suddenly can’t find her daughter, the feeling is all too familiar. Mother and daughter will need to address old secrets and the emotional impact they have wrought before they can reconcile with each other, and, finally, with themselves.
