You are five years old, two sisters and you long for a little brother to play boy games with. One evening your parents announce that you will have him, this brother, and that he will be special. You are overjoyed: special, for you, means ‘superhero’. You even choose his name: John. Then he is born, and little by little you understand that yes, he is different from the others, but he does not have superpowers. Eventually you discover the word Down, and your enthusiasm turns into rejection, even shame. You have to go through adolescence to realise that your initial idea was not so wrong. Let yourself be overwhelmed by John’s vitality to conclude that perhaps, a superhero, he really is one. And that in any case he is your best friend. With Mio fratello rincorre i dinosauri (My Brother Chases Dinosaurs) Giacomo Mazzariol has written a coming-of-age novel in which he did not need to invent anything. A book that amazes, moves, amuses and makes you think.
