This CBC Radio Special looks at how and why secrets take hold in families. Why do we decide not to share truths with those closest to us? What are the long-term effects of keeping secrets on families? And what happens when those secrets are revealed? Host Diane Flacks explores secrets in her own family, especially those kept by her mother who was born in Siberia during the Holocaust. Flacks speaks with chaplain and author Kerry Egan who offers both personal and professional insight into secrets. She also meets clinical psychologist, professor and author Robert T. Muller, a professor at York University who talks about his book on secrets and the effects of intergenerational trauma on families.
