This is a wide cast for a thriller, with Kate Marino at the center. She is a police K-9 handler and widow juggling her daughter Ivy, her dogs, and the search for her missing niece Alice.

Main Characters

Kate Marino

Protagonist

Police officer and K-9 handler, mother of thirteen-year-old Ivy and widow of Anthony. She searches for her missing niece Alice with her dogs while balancing single parenthood, buried trauma from her abusive father, and the pressures of being a woman in law enforcement.

Arc: Kate is repeatedly sidelined from the official Alice Vega investigation but keeps working unofficially, eventually tracking the killer to his cabin and being captured. She escapes with Alice, confronts her father, and slowly starts to heal by accepting family support and a possible relationship with Roy.

Jaxon Hill

Arc: Jaxon remains self-justifying throughout, framing his killings as forced on him and claiming he only wanted to help his captives.
