I don't have much time to write anything meaningful about the book right now, but I have finished it. Initial reaction was that it was, by default (I think), the best modern Italian book I have ever read and the second best representation of a synesthesia-like reaction to food (first being the fireworks the rats imagine when they eat in "Ratatouille"). I'll try to post something of substance later on this week.
I've read only one of the books on the Tournament of Books site - the Junot Diaz one. It was really good, so I guess I'm rooting for it.
