Title: Three Steps Over Heaven
Passage: Rome.  Stefano Mancini, called "Step" and Fabrizia Gervasi called "Babi" belong to two completely different realities.  She is a model student, has friends and courtiers and is divided between home, school, and private elite housewives.  He is a hard-pasted teppist and troubled family relationships (especially with her mother) who spends her time in clandestine races in motion and scorribande.  Fate will bring them to meet and fall in love, though Babi is the only witness to Step's aggression to a poor man who has split his glasses with a head and intends to testify against the boy.  Their story takes off according to the logical banal of alchemy between opposites and the opposition of her parents.  Babi is introduced to a world that is unknown to her, she begins to marinate the school, to study less and to get hurt in trouble, but it seems that nothing is able to divide it from Step.  The two have never been in love before, but Step's violent and unscrupulous life will go back to Babi several times until, after the death of his great friend Pollo n who in turn was engaged with Pallina, the best girlfriend of Babi, she will decide to leave it permanently.
