Hannah Halston, Tad’s sister, refuses to believe the official story that her brother went on a vengeful killing spree. She’s doing her best to clear his name, which brings Darek’s partner, Special Agent Lizzy McNamara, even closer to his criminal past.
Meanwhile, whoever is targeting the Zodiacs has their sights on Logan Miller. His life is complicated enough already, with his struggling career and bitter relationship with an older woman, but when he meets Hannah Halston at her brother’s funeral, lending a sympathetic shoulder turns into so much more. He’s determined to end things with the older woman until she tells him she’s dying. Stuck between a rock and hard place, does he continue his relationship, or go where his heart tells him? Will the killer choose for him?
