Luisa "Lu" Brant is the newly elected--and first female, state's attorney of Howard County, Maryland, a job in which her widower father famously served. Fiercely intelligent and ambitious, she sees an opportunity to make her name by trying a mentally disturbed drifter accused of beating a woman to death in her home. It's not the kind of case that makes headlines, but peaceful Howard county doesn't see many homicides. As Lu prepares for the trial, the case dredges up painful memories, reminding her small but tight-knit family of the night when her brother, AJ, saved his best friend at the cost of another man's life. Only eighteen, AJ was cleared by a grand jury. Now, Lu wonders if the events of 1980 happened as she remembers them. What details might have been withheld from her when she was a child?
