A prison guard is found dead in a women's correctional facility. A fellow guard—bewildered and betrayed—is the only suspect.

Attorney Lily Greco never meant to practice law again. After a career-ending mistake, she retreated to her small Pennsylvania hometown, haunted by her sister’s murder and the life she lost in its wake. Encouraged by her grieving mother, she has taken over the martial arts studio her sister once ran—a beloved community hub for local kids and families. But every class is a reminder of the sister she lost.

When the mother of one of her young students is arrested for a seemingly airtight prison murder, Lily can't turn away. But this is no ordinary day in court. She's never tried a murder case, and the evidence against her client is devastating. As she peels back layer after layer of deception, she begins to suspect there’s far more to the story than the police have considered.

To win justice for her client, Lily must face her own demons and return to the courtroom for the fight of her life. If she loses, a vulnerable mother will be buried by the system—and whatever is hiding behind the prison walls will stay buried with her.
