If you are Catholic and are interested in this book, you need to know there is explicit anti-Catholicism in it. It's the standard, "Catholics worship Mary, Peter wasn't the head of the Church, we're really pagans".
I got this book, and while it is beautiful (and huge!), I took exception to misinformation and lies.
Oh, and Protestants might want to be aware too, the author thinks most of you are doing and believing the wrong things also.
