Review of The Wolf Princess-Cathryn Constable

In a gray, dreary boarding school in London, a young orphan girl dreams of a snowy landscape.  When Sophie and her two best friends are suddenly allowed to go on a field trip to St. Petersburg, Russia, she jumps at the chance.  Abandoned in a snowy blizzard, the three friends are whisked away to a decrepit castle deep in the woods.  There they meet a princess who invites them to stay with her, but things aren't what they seem and the longer they stay, the more the mystery deepens.  This was a great fairy tale/ Russian folk tale of a novel - thoroughly enjoyable.  4 Elves - highly recommended for middle grade readers
