On a snowy Christmas morning, Holly Judge awakens with the fragments of a nightmare floating on the edge of her consciousness. 13 years ago, she and her husband Eric adopted baby Tatty, their pretty, black-haired Rapunzel, from the Pokrovka Orphanage 2. Now, at 15, Tatiana is more beautiful than ever - and disturbingly erratic. As a blizzard rages outside, Holly and Tatiana are alone. With each passing hour, Tatiana's mood darkens, and her behaviour becomes increasingly frightening, until Holly finds she no longer recognises her daughter.
