Blood Brother: The gene that rocked my family offers a brave and nuanced take on one of the most radioactive issues of our times: genetic testing. When her beloved brother Jim is diagnosed with Huntington's disease—a fatal brain disease—author Mona Gable is suddenly thrust into alien, frightening territory without a road map to guide her. Still, as she recovers from the shock of her brother's death, decisions must be made. To get tested or not? To inform her children that they may also be at risk? To speak openly and publicly about a disease that historically has been cloaked in secrecy and shame? This is a must-read for anyone who has grappled with similar issues or who suspects that they, too, may have inherited a deadly gene.
