I have to admit I havn't read the Last Don yet. But i'm definately going to get it as it sounds great.

The Sicilian is amazing. I havn't came across many people who havn't enjoyed that book. In fact i've came across about one person so far. It's also based on a true person 'Salvatore Giuliano.' A hero to the Sicilian people in the 40's. A must read.
