Dear Sister: A Memoir of Secrets, Survival, and Unbreakable Bonds by Michelle Horton

The heartbreaking story of a woman incarcerated for killing her abuser, told by her sister, highlights systemic wrongs and the resilience of a family in trauma.

Dear Sister: A Memoir of Secrets, Survival, and Unbreakable Bonds is a harrowing story, a call to action, and a love letter between sisters.

In their 20s, Michelle Horton and her sister, Nikki, were very close, working together to raise Nikki’s two children and Horton’s son. Horton thought she knew everything about her sister’s life, and so was entirely caught off guard by the emergency call. Her niece and nephew’s father was dead. Nikki had killed him. He had been abusing her horrifically for years, and many members of the community had known it, had been working actively to get Nikki out. Horton was told to come and pick up her sister’s children, ages two and four, immediately.

In the months and years that followed, Horton’s life was consumed by the work of single-parenting three children while raising money for her sister’s legal defense, becoming an amateur expert on criminal law and the psychology of abuse, and advocating for survivors’ rights. The high-profile 2019 case of Nikki Addimando resulted in her conviction of second-degree murder and a sentence of 19 years to life in prison. Despite extensive evidence, the judge concluded that Nikki was not a victim of abuse.

Horton’s narrative (with supporting evidence) is available elsewhere, but she additionally brings to her memoir a close, personal account of Nikki’s trauma and that of the three children involved, the deep connection between sisters, and the continuing failure of the legal system adequately to handle abuse victims when they appear as criminal defendants. Horton delves into the sisters’ childhood, including earlier instances of abuse, and the culture in which so many–including the author–failed to recognize the signs of Nikki’s suffering. Keeping silent about her abuse did not serve Nikki in the end, but Horton observes that other victims will not be encouraged by Nikki’s experience to speak up.

The stories Horton relates are heartbreaking. She does not shy away from graphic descriptions of the brutal abuse Nikki experienced, which some readers will find difficult to read. These details do not feel gratuitous, but rather central to the painful but necessary account Horton offers. Her concern extends beyond her own family, to other victims of intimate partner violence who enter the justice system as criminals. Dear Sister is not only Horton’s story and Nikki’s story, but also an urgent appeal for reform. Heartfelt, disturbing, but ultimately hopeful, this memoir is an important part of an ongoing conversation, and a tribute to sisterhood.
