Novelist Aaron Holland Broussard is shattered when his daughter Fannie Mae dies suddenly. As he tries to honor her memory by saving two young men from a life of crime amid their opioid-ravaged community, he is drawn into a network of villainy that includes a violent former Klansman, a far-from-holy minister, a biker club posing as evangelicals, and a murderer who has been hiding in plain sight. Aaron's only ally is state police officer Ruby Spotted Horse, a no-nonsense woman who harbors some powerful secrets in her cellar. Despite the air of mystery surrounding her, Ruby is the only one Aaron can trust. That is, until the ghost of Fannie Mae shows up, guiding her father through a tangled web of the present and past and helping him vanquish his foes from both this world and the next.
