I recently bought a book called Deadly Viper: Character Assassins by Mike Foster and Jud Wilhite and it has opened the door for a lot of great conversations with friends. The book approaches integrity and character issues from a ninja standpoint (do I even need to say more?). We all need people who will speak truth into our lives and I believe this book provides a lot of good insight into character assassins that we need to be looking out for. You can download the audiobook for for free here so check it out and see what you think. I would still recommend buying the book for all the sweet ninja graphics.
