Well, from what I hear "The Godfather's Revenge" will take plave from 1963 to 1972. Maybe the book will habe a chapter or two about Vincent rising through the ranks of the Mafia and his first encountar with Joey Zasa. I remember in the beginning of Godfather III, Michael states he offered Vincent an offer to work in legitamite buisness but turned it down. Hopefully Winegardner will have in the book.
