In this touching and sometimes humorous story of hardship and triumph, Harriet S. Mosatche chronicles her life with her brother Ian, whose severe developmental disability shaped her values and interests and led to her decision to pursue a career in psychology. Fingerprints on My Heart is both a personal story and a historical journey through the changing legal and societal views toward those with disabilities. Mosatche shares stories from an adolescence in a chaotic household, her romantic relationships, raising two children, the illnesses and deaths of her parents, and her educational and career choices and challenges-all while fighting the rampant prejudice against those with disabilities and trying to obtain humane care for Ian.
