When Jennifer Brady returns to Northern Arizona University for her sophomore year, she quickly becomes a big sister to her new roommate, Beth Rankin, a brilliant yet sheltered sixteen-year-old freshman. For a homeschooled Beth, college is her first taste of both freedom and unfettered access to the internet, and Jenny is concerned that she's too naÞive and rebellious for her own good. Her worries are well-founded because one day Beth vanishes, prompting Jenny to alert campus authorities, local police, and her mom, Sheriff Joanna Brady—who calls in a favor. Beth is found, but Jenny's concern has unwittingly put her in the crosshairs of a criminal bent on revenge. With Christmas vacation approaching, and Beth at war with her parents, Jenny invites Beth to the shelter of the Brady home. While Joanna is sympathetic, she's caught up in a sensitive case—an officer-involved shooting that has placed the lives of two young children in jeopardy—leaving her stretched thin to help a fragile young woman recently gone missing and endangered.
