Personality Types: Using the Enneagram for Self-Discovery by Don Richard Riso
My rating: 4 of 5 stars
If you want to know more about the Enneagram, this is an excellent overview of the framework. It really helped me to delve deeper into each type and better understand the core dynamics and levels of development for each. This is a great addition to my Enneagram library! Well organized and I was able to easily connect the information in it to my own life.
