Query: Interesting little book!

I did not know what to expect when I purchased this free book for Kindle and was pleasantly surprised. It's clear, concise style made for relatively quick reading. The author presents several interesting perspectives on areas that I thought I knew fairly well. I copied down several statements he made as they were insights for me. I would recommend it for anyone studying or wishing to know more about the Holy Ghost. I especially think non-Catholics would find much insight in this book written from a Catholic perspective. I did.
