"One night, Franca has a dream about a marvelous queen who lives in a dark cave, deep in the forest. She cannot sit still until she knows if her dream is true. So with her younger sisters, Carmela and Tomasina, Franca ventures into the forest at the end of their garden. As they travel deeper through nettles and thickets, drawing closer and closer to the cave, the world shifts, and everything shrinks and expands at the same time. Here, they meet beasts and creatures that shock and delight them, and they escape horrible things that frighten them. They learn to be brave, to be bold, to face their darkest fears."
