In Her Bones by Kate Moretti
Fifteen years ago, Lilith Wade was arrested for murdering six women. After a death row conviction and media frenzy, her daughter Edie is just trying to survive out of the spotlight, but has a disturbing secret: an obsession with the families of Lilith's victims. Then one man is found murdered and she becomes the prime suspect. Edie remembers nothing of the night of the murder, and must get to the truth before the police-or the real killer-find her.
