Comparative Religion for Dummies looks at the three Abrahamic religions (Judaism, Christianity, Islam), their common ancestor in Abraham, their similarities and a basic overview of their beliefs. I borrowed this book from the library and this is the first 'For Dummies...' book that I have read.
It covered the basics of the three religions so it was informative but lacked any depth. It is an interesting read as an introduction to the three religions, however, I did find it a bit boring and monotonous. I doubt I will read any 'For Dummies...' books again.
