Publisher: AB Books
Tired of the cruel mistreatment they endure from their wicked stepmother, who is also a witch, a brother and sister run away from home one day. They wander off into the countryside and spend the night in the woods. By morning the boy is thirsty, and so the children go looking for a spring of clear water. But their stepmother has already discovered their escape, and has bewitched all the springs in the forest. The boy is about to drink from one, when his sister hears how its rushing sound says "Whoever drinks from me will become a tiger".
