Order of Reading

Is there an order to read the novels by Puzo? I have The Godfather on order, and if I don't get it soon, I'll just go purchase it. But I am picking up The Sicilian tomorrow. So that I know in advance, is there an order in which I should read the novels for them to make more sense to me, such as

The Godfather
The Sicilian
Omerta
The Last Don

??

Yeah!

Care to elaborate?

Well the Sicilian contains a little bit about the time when Michael was exiled in Sicily - but not too much. So you could probably read that before the Godfather without any problems, but it might be better to read it after.

Well, I just got the Sicilian to read today. I have not yet read the Godfather novel though, but I'm hoping this will still be a good read nontheless.
