Since the tragic death of her fiancé one week before their wedding, Fern O’Connor had buried her grief in her work as a nurse at College Hospital. She thought she’d buried her heart with it. But when her wealthy young patient, Bob Creasey, reached out to her in his desperate emotional need, she found herself responding not just as a nurse, but as a woman. And when her anger at the brilliant and arrogant Dr. Stanley Lowden began to change to excitement, Fern had to choose between faithfulness to a memory and her duty—as a nurse and as a woman.
