“A beautiful reminder that fairy tales are at their best when they illuminate the precarious balance between lighthearted childhood and the darkness and danger of adulthood.” —School Library Journal (starred review)Elena Rudina lives in the impoverished Russian countryside, and there is no food. But then a train arrives in the village, a train carrying a cornucopia of food, untold wealth, and a noble family destined to visit the Tsar in Saint Petersburg—a family that includes Ekaterina, a girl of Elena’s age. When the two girls’ lives collide, an adventure is set in motion, an escapade that includes mistaken identity, a monk locked in a tower, a prince traveling incognito, and—in a starring role only Gregory Maguire could have conjured—Baba Yaga, witch of Russian folklore, in her ambulatory house perched on chicken legs.
