'Not having a child can change your life as much as having one.'
Grace has returned to London after twenty years abroad to manage her dying mothers affairs. When she receives a blank Mothers Day card in the post, she is confused and unsettled. Who could have sent it to her and why? She isnt a mother.
Another Mothers Day card arrives. Then come the silent phone calls. Haunted by disturbing flashbacks, Grace starts to unravel. Someone is out to get her. Someone who knows what she has done. Someone who will make her face the past she has run from for so long.
