I've read several mafia books and most of them have been good. However, I hated (with a great passion) "Mafia Princess" by Antoinette Giancana. She was wayyy too jumpy in the whole book. I guess it was hard to like it once I read Double Cross by Chuck Giancana. To me, he was a better writer and less "Oh My God, look at me I'm spoiled". Just my 2cents.
