Just started reading Last Don, I'm up to book 4. Pippi and Cross AFTER Boz swims around the fence.

Are the Claudia, Athena, Skannet parts like the Fontane, Lucy. Nino parts in The Godfather? unimportant?

I've read 100+ pages and still don't know what the plot is.

Just basicall Boz harasses his wife, lots of guys screw Claudia, and Cross moved away from his father. What's the point? Why is it called the Last Don?
