Kathryn soon realizes that she and Carson have a lot in common. Not only will they be starting their freshman year of high school together at the end of the summer, Carson's mother is dying-something Kathryn has already experienced, years before. Before long, they're inseparable. For Kathryn and Carson, everything seems nearly perfect-until their happiness is overshadowed by the specter of Huntington's disease, which threatens to destroy everything they hold dear.
