I wonder if Veronesi thought that he would never be able to replicate the success of Caos Calmo, so he just decided to milk its main character for an unnecessary sequel.
Mum liked this book. I respectfully disagree, at least partially. To me it's closer to the latest book by Ammaniti than it is to Caos Calmo. Same Rome, same need to throw in one of the supposed most beautiful women in Italy, same improbable (though often rather dull) encounters with minor characters.
So, I'd class it as a harmless quick read, but would never say I liked it.
Actually, one thing that I can truthfully and openly say that I did NOT like is the return (resurrection?) of the main character's sister-in-law, with unfinished business and unfulfilled love and career aspirations. I'd take the Roman chav that our protagonist dumps on the road any day of the week (maybe not as a life companion, but surely as a fictional character).
