I've just finished the book, I loved it, especially the way Michael and his father were included.
I didn't like the ending too much though, I really wanted Turi to make it to America.
I also thought that it would have been better if Hector had planted the note 'so die all who betray Guilliano' in Aspanu's pocket on his own, without being asked to do so by Don Croce, I didn't like the way that Croce was invlolved in that part, after all it was all down to him that Turi was dead.
A very good book - I feel I should now see the film, though I think I will regret it!!!
