After a 30-year absence Agnes is returning to Australia, the country of her birth, at the request of her aging, narcissistic mother. Having undergone a long period of psychotherapy she now entertains a hope that burning questions will be answered, haunting mysteries solved, and buried memories encouraged into the light. Something has blighted her life since childhood. Something has cast a long shadow over her existence, affecting her ability to grasp at life fully, to develop sustained relationships and to appreciate her own sense of self-worth. In a leafy suburb of Sydney, a chance meeting in front of her early childhood home resurrects memories of a traumatic event. This represents the moment young Agnes starts to realise, and repress, feelings of confusion, cruelty and alienation from those who should love her the most. Agnes—A childhood betrayed and reclaimed is the revelatory, true account of one woman's determination to grapple with—and heal—the ills that have beset her past.

As the missing pieces of the family puzzle gradually fall into place this brave woman's search for the truth is vindicated. Decades of mental health challenges, from amnesia to acquired dyslexia to self-limiting thoughts are ultimately overcome, and an irrepressible spirit released.
