As a snowstorm wreaks havoc in the mountain town of Crooked Creek, a woman is found buried in ice. Detective Ellie Reeves is first on the scene. Examining the body, she finds frozen blonde hair, pink nail polish and a silver heart necklace engraved with Mine Forever. Ellie has first-hand experience of the monsters that lurk in the mountains--her childhood is testament to that. She vows to catch this one, but shes up against the brutal weather, with snow covering footprints and making forensics impossible. Frantically trawling through missing-persons reports, Ellie identifies the victim. Nadine Houser disappeared eleven years ago. Where has she been all this time? Why was she only murdered now? As storm clouds roll in, another girl is reported missing. Ellie retraces the steps of Ginger Weston who was renting a cabin in the mountains. She discovers a gold chain in the snow, spotted with blood. The killer is accelerating, and its just a matter of time before more innocent lives are robbed. With the town blaming Ellie for the missing girl on her watch, and everyone fearing for their safety of their daughters, its down to Ellie to solve the toughest case of her career. But when the killer comes after her, will she live to save Crooked Creek from its ruthless monster?
