Only by Blood is a novel of the search for roots, mother-daughter love, and family reconciliation. Spanning over 60 years, this story tells about the lengths to which mothers will go in order to save their daughters and the secrets they will keep to protect them from pain. Set in the broader context of the fraught relationship of Poles and Jews during and after the Second World War, it depicts the circumstances that made some ordinary people behave heroically while others betrayed their friends and neighbours.
