We chat to Cathy Rentzenbrink about her book The Last Act of Love. In 1990, Cathy's brother Matty, was knocked down by a car on his way home from a night out. Sitting by his unconscious body in hospital, holding his hand and watching his heartbeat on the monitors, Cathy and her parents willed him to survive. They did not know then that there are many and various fates worse than death.
