90 Days to Live is a dual-perspective memoir that chronicles the experience of a husband and wife facing a life-threatening cancer diagnosis and the prognosis of limited time. Written through alternating first-person voices, the book follows the emotional, medical, and personal journey that begins with unexpected symptoms and leads to a diagnosis of Non-Hodgkin's Lymphoma. It documents clinical consultations, discussions about chemotherapy and prognosis, family conversations, and the psychological impact of confronting mortality while raising children and managing a growing business. The narrative combines medical detail with intimate reflections, capturing fear, doubt, anger, faith, and resilience as the couple navigates complex treatment decisions and seek understanding beyond standard protocols. Intended for readers interested in cancer memoirs, personal resilience stories, and family-centered accounts of serious illness, the book offers a narrative and experiential approach rather than a clinical manual. It provides insight into the patient and caregiver perspectives, the dynamics of medical decision-making, and the emotional realities of living under a time-bound prognosis. Through storytelling grounded in lived experience, it explores themes of hope, partnership, research, and determination in the face of uncertainty, making it relevant for individuals confronting illness, supporting loved ones, or seeking reflective accounts of health crises and survival journeys.
