Story sometimes hard but addictive

I did not know that Italian is the author whose first novel (which also explains that ...). The novel is exciting, he describes almost cynical sometimes extreme emotions (fear, pain, love, guilt, shame, ...) of these two satellites that cross, recross adolescence to adulthood. I find that the author succeeds the end of the novel, which was perhaps one of the difficulties (it does not presume what happens at the end!).
