11 missed calls

11 Missed Calls by Elisabeth Carpenter, Anna's mother vanished thirty years ago. Anna believed her mother was dead, but suddenly, she starts receiving notes—could they be from her mother? Her father remarried her mother's best friend, raising questions about a possible affair. Anna is struggling; she knows little about her mother, and no one will disclose the events of that night. Frustrated by claims of her insanity and urged to forget her mother, Anna seeks her husband's support, only to discover a photo that suggests he might be unfaithful.
Previously, Anna had obsessively followed a woman resembling her mother, leading her family to worry she might repeat the past. The narrative alternates between the present and thirty years prior, revealing characters whose identities may not be as they seem. As Anna feels increasingly threatened and suspects she's being followed, she must unravel why someone is determined to conceal the truth from her.
