Book excerpt: Detective Olivia Mast would rather run through gunfire than return to her former Amish community in Unity, Maine, where she killed her abusive husband in self-defense and witnessed her family's murder. She soon finds out that there are even more dark secrets in Unity than the ones from her own past, just waiting to be unearthed from the farm soil. After an Amish man is murdered, the community will not pursue justice or answer questions from the police, so she begrudgingly dons her old prayer kapp and heads to Unity to investigate the murder undercover.
