THE GOD DELUSION by Richard Dawkins
On the same theme, The Magic Animal..Philip Whylie. (religion as superstition, likely out of print)
This book had a great impact/affirming for me, but is only of value for those who are open /searching and have a mind open to the thesis as with your book.
I've read so many books and I've learned something from each of them. Lucky us readers. Always learning. Life is exciting.
