A memoir about life (and near-death) with a genetic heart condition. This book is composed of many voices: physical and metaphysical; medical and mystical. It's a love story, a heroine's journey and a medical drama that explores the fragility and resilience of the human heart. The journey portrayed reconciles the author's family heritage of natural healing and the conflict that arises between a holistic and spiritual orientation with western technology. This literary non-fiction narrative weaves between personal and mythic realms, depicting a mother's love for her children at risk and a woman's love for a man who stands by her in the darkest hours. "Heart's Oratorio" provides examples of the miraculous, offering hope to those dealing with chronic and life-threatening illness.
