Daco, if you want to read just for the sake of it...sure why not, Sifakis´s book is good. But if you want to learn about the Mafia, I strongly recommend:

- Joe Bonanno´s (with Sergio Lalli) "A Man Of Honor";
- David Critchley´s "The Origin Of Organized Crime In America";
- Alan Block´s "East Side, West Side";
- Tim Newark´s "Lucky Luciano";
- Gene Mustain´s and Jerry Capeci´s "Murder Machine";
- Bill Bonanno´s "Bound By Honor";
- Bill Bonanno´s "The Last Testament of Bill Bonanno";
- Lee Lamothe´s And Adrian Humphrey´s "The Sixth Family";
- Mike Dash´s "The First Family";
- Selwyn Raab´s "Five Families";
- Jonathan Kwitny´s "Vicious Circles";
- Howard Abadinsky´s "Organized Crime";
- Joseph Pistone´s (with Richard Woodley) "Donnie Brasco; My Undercover Life In The Mafia".

Theese books are all good, solid informative books that are easy to read. They are stuffed with well researched info.
