A breathtaking memoir about two sisters and a high-profile case: Nikki Addimando, incarcerated for killing her longtime abuser; and the author, Michelle Horton, left in the devastating fall-out to raise Nikki's young children and to battle the criminal justice system.

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. Determined to reunite her sister with her kids, Michelle launches a fight to bring Nikki home, squaring off against a criminal justice system designed to punish the entire family.

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. She retraces their childhood, searching for clues to explain how so many people could have been blind to her sister's dangerous situation. Dear Sister is a profound, intimate story about not just surviving trauma, but turning it into hard-won wisdom. It is a story of resilience and the unbreakable bond of family.
