The summer between fifth and sixth grade is a time of transition, especially for Ernesto "Quattrocchi", ten years old and half a life. Between his mother and father who no longer seem to love each other, between the town bullies and a badass friend, between his being a squacquera and a new-born love, between his grandmother's blue eyes and Donna Lucia's blind and omniscient ones, the village witch.
Every now and then the world is too noisy, then you feel overwhelmed: you need to get on your bike, your glasses and your cyanometer. It is precisely in one of his explorations with Cardella that he finds a suitcase containing an ancient legend; now he just has to find everything he needs to break the curse.
A thoughtful and magical diary of the sky, and of everything that changes on earth.
