At age eighty-three and in failing health, Olivia Morrow knows she has little time left. The last of her line, she faces a momentous choice: expose a long-held family secret, or take it with her to her grave. Olivia has in her possession letters from her deceased cousin Catherine, a nun, now being considered for beatification by the Catholic Church. These letters reveal that, at the age of seventeen, Catherine gave birth to a son and gave him up for adoption and they identify the father as Alex Gannon, a world-famous doctor, scientist and inventor of medical patents. Now, two generations later, thirty-one year old paediatrician, Dr. Monica Farrell, Catherine's granddaughter, stands as the rightful heir to what remains of the Gannon family fortune.
