While I read many books during my RCIA classes, I found this to be the only detailed guide for attending Mass and receiving the sacraments. The author -- who is a convert herself -- explains rules and traditions carefully and fully. She saved me from embarrassing myself because I didn't know what I was doing. I still refer to this book often!
When I married my husband (an agnostic) in the Catholic church, he had no idea about what was going on. Most wedding ceremonies in the media are Protestant and he thought all weddings were like what he saw on tv. This book helps him understnad what's going on in any Catholic ceremony. Now he knows in what parts he can participate in, which ones he can't, and why.
I highly recommend this book for anyone in a "mixed marriage." Many Catholic family affairs involve the Church and non-Catholics need to know what's going on!
