Megan Collins’s standalone novels each present a self-contained story of family secrets and psychological suspense. The Winter Sister (2019) starts with a woman confronting her mother’s past and her sister’s unsolved death. Behind the Red Door (2020) involves repressed childhood memories triggered by a missing-person case.
The Family Plot (2021) takes a darkly unusual approach, centering on a family that celebrates death as part of their upbringing. Thicker Than Water (2023) and Cross My Heart (2025) continue her pattern of placing ordinary people in situations where the truth about their loved ones turns out to be far stranger and more dangerous than expected.
