With a pair of new knees, Mae Kozlowski hit her 80th birthday in full stride. She had recently completed the cruise of a lifetime. She was the beloved matriarch of her family, encouraging, supporting and - most of all - loving her children, their spouses and grandchildren. She was still an active volunteer in her community and a vital member of her church. Less than 6 months later, though, her world changed in a instant when she was told in a hospital emergency room that she had a brain tumor. This is the story of the spirited, humor-filled, God-centered woman's final 18 months, and glimpses into her life B.C. (Before Cancer).
