On June 23, 2030, Nadia Mallorie Willis, then 13 going on 14, killed her own biological grandfather, Percy Barnett, in an act of self-defense during his invasion of her family's home in Luna Vista, California. Realizing that her mother's severe mental illnesses stem directly from having been abused by Percy as a child, Nadia embarks on a journey that will continue for the remainder of her 120-year lifetime, brutally and ruthlessly murdering physical and sexual child abusers.
