It's a tough read (if you're used to not only easier English but also less though provoking stuff). It's VERY good though! Basically it's a senior devil writing letters of instruction to his apprentice about how to win souls for hell. Reason it's such a good book is because it makes you think about how you're living your life and does anything in the book match up to things that you don't think twice about. Instead of how most religious books are about talking about how to enter heaven, this one shows you the other side of the coin. Not only a wake up call but also very interesting to think about. You should definitely give it a read
