Query: This book is of little value to non-Catholics

I bought this book hoping that my non-Catholic wife might learn about some of the Catholic practices. Unfortunately, the book answered none of her fairly simple questions. My wife attended mass with me and came away with so many questions: 1. Why do you kneel during some parts? 2. What is a deacon? 3. What is the difference between a Dominican, a Franciscan, a Jesuit, a Redemptorist? 4. What do you mean by "Mystery of Faith"? I could go on and on ... but I won't find simple answers to any of these questions in this book.
