Main Characters
Kate Marino
ProtagonistPolice 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
AntagonistA police officer and the main killer, who hunts women, keeps some imprisoned in a remote cabin, and kills those who try to escape.
