Rachael and Deborah weren't just sisters—they were best friends.

With a 14-year age gap, Deborah helped raise her little sister, becoming her safe place, confidante and one of the most important people in her life.

Eight years later, Rachael is still trying to understand how someone who once felt like family and a best friend could become a stranger.
