Mapping Fate: A Memoir of Family, Risk, and Genetic Research - Alice Wexler I think this book could be very interesting. I think it will cover both the scientific side of Huntington's disease, the implications of genetic testing and also the emotional impact a hereditary disease, not just Huntingtons, has within a family. And I liked the text, the way the author expressed herself in the book's first pages visible at Amazon. Thank you Lynne for bringing this book to my attention.
