Little Book o' Piracy

The Book O' Piracy is a book that you get after completing the Cabin Fever quest. After gaining access to the pirate town of Mos Le'Harmless, you need to use this book to understand what other pirates are saying. If you read it, it will tell you a bit of pirate slang, but all you need to do is carry the book to understand them.

After completing the quest, you can also find the book in the shelves in your house.
