Gazing out the cabin window at the raging blizzard, fear suddenly floods through her as she feels a stranger’s hand clamp across her mouth. No one can hear her stifled screams as she is dragged from the couch by the fire out into the snow.

When 17-year-old Savannah Devenish vanishes from her family’s remote vacation cabin in Minnesota, FBI Agent Tori Hunter races along treacherous icy roads to be first on the scene. Savannah’s parents are frantic with worry for their beautiful, carefree girl. Haunted by memories of her own missing sister, Tori vows to do whatever it takes to reunite this family.

When the police uncover that Savannah’s father, Jacob, was having an affair, they suspect his involvement, but Tori is convinced his despair is genuine. Her close relationship with the chief detective means the team won’t listen, so Tori strikes off alone, persuading Savannah’s distraught best friends to share their secrets. It seems this "good girl" was sneaking out to parties to meet up with a mysterious man....

Then another teenager is snatched from the street, snowy footprints and a discarded hot chocolate cup the last trace of her. The girls are the same age, strikingly pale and blonde. Is a twisted collector stealing them away? And what chance is there that they are being kept alive?

With a deadly snowstorm closing in, Tori battles the elements - and her own team - as she follows the trail to an abandoned cabin by a frozen lake. In the basement are bedrooms filled with clothes for teenage girls. Tori was too late to save her own missing sister 20 years ago, but can she find these girls before they disappear forever?

An utterly addictive and twisty crime thriller that will have your heart in your mouth.
