In September 2017, a knock on the door upends Michelle Horton’s life: she learns that her sister has just shot her partner and is now in jail. Stunned to find herself in a situation she'd only ever encountered on TV or in the news, Michelle rearranges her life to raise Nikki's two young children alongside her own son.
 
During the investigation that follows, Michelle is shocked to learn that Nikki had been hiding horrific abuse for years. She realizes that in order to understand the present, she must excavate the past, and search for clues to explain how so many people could have been blind to her sister’s dangerous situation. Determined to reunite Nikki with her kids, Michelle launches a fight to bring Nikki home, squaring off against a criminal justice system designed to punish the entire family.
 
Since Dear Sister’s original publication, Michelle’s fight—alongside a tireless network of supporters—has resulted in Nikki’s release from prison. With a new chapter, an update from Nikki, and never-before-seen photographs documenting the homecoming, this edition provides a touching new conclusion to a profound, intimate story of resilience and the unbreakable bond of family.
