Shared trauma has driven them a world apart; they will need to find each other again to begin to heal. Nightmares still haunt Chloe thirteen years after she lost her baby sister. Her mother, Jules, with a busy tech career and long history of chronic pain, has little time for Chloe. After Chloe drops out of university to travel for a year, Jules's OxyContin dependency quickly becomes a problem. 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 completely and spend some time alone. When Jules suddenly can't find her daughter, the feeling is all too familiar and she becomes determined to find her. Mother and daughter will need to address old secrets and the emotional impact they have wrought on both their lives before they can reconcile with each other and, eventually, with themselves.
