Petronella is not an ordinary witch, but a kind and cheerful one. And she doesn’t live in some hut in a dark forest—instead, in this book, a good little witch Petronella and her friends Luis and Lina are in for unusual adventures. A circus comes to their town on tour. Lina and Luis meet the troupe kids and sneak behind the scenes. To their horror, they discover that the circus performers aren’t happy with their lives, the director keeps falling asleep, and evil magic and a magician are running everything. Maybe Petronella can help them? For children of middle school age.
