“In the words, Isidor. There lies the magic!” It is the best, the most important job in the world. The big dream of little Isidor: to guard his own invisible moon rope. To patrol tirelessly on the rooftop, testing the rope with his hand to see if it’s tied well...

Bella does it every night! But the wizard Livorno always tells him no. He trembles at the thought that the knot might come undone and the moon will drift away. And then, farewell world. The caliph will not spare them.

But Isidor has made up his mind. He will become the guardian of the moon, let the world fall apart. For one night. Even for one night...

A story about dreams, friendship, struggle. And about the miracles that spring from our words and embrace the whole Earth.
