For ppl into Mafia books, i highly recommend reading
"Gomorrah - Italy's other Mafia".
this is an absolute dope book, basically its a investigative report on the Gomorrah. All the content in it is true. Apparently the Author is now hunted down by the Gomorrah, he got until Christmas to live.
You can understand why because the book goes into incredible detail over every aspect of the organisation. Even to the nicknames of each member.
