Betty O'Neill grew up knowing very little about her father, Antoni. She knew that he had fled Poland after World World Two, that he had disappeared overnight when she was just an infant, and that his brief reappearance when she was a young adult had been a harrowing, painful ordeal. Fifty-five years after he deserted her family, Betty becomes determined to solve the mystery of her absent father and discover exactly who was Antoni Jagielski. When her search takes her to Poland, Betty unexpectedly inherits a family apartment from the half sister she never knew - a time capsule of her father's life. Sifting through photos and letters she begins to piece together a picture of her father as a Polish resistance fighter, a survivor of Auschwitz and Gusen concentration camps, an exile in post-war England, and a migrant to Australia. But the deeper she searches, the darker the revelations about her father become, as Betty is faced with disturbing truths buried within her family. Honest, compelling, and meticulously researched, The Other Side of Absence is an elegant debut memoir of resilience and strength, and of a daughter reconciling the damage that families inherit from war.
