This book contains the normal Book of Mormon writings in it. They haven't changed anything. They simply added some helpful features. Here is a sample page that I scanned into the computer (obviously a bad scan job!). Note how the chapter is subdivided by red titles within that chapter. This gave us a clear stopping and starting point while reading. Sometimes we would read a whole chapter or two and sometimes we just read from one little red subtitle to the next and called it good if the kids were being nuts.
Notice how there are also quotes from latter-day prophets, explanations, word definitions, questions, etc. on each page. We read through these also with our kids to help them understand things better.
The Book of Mormon is a true book, in fact THE most true book on this earth. We love to read it together each night and have a testimony that our consistent scripture study (however short) has made us a stronger family. If you are struggling with family scripture study, I would recommend spending the money to buy this book. I think it was around $50.00 but worth 10 times that much to us.
These are the last days. There is no time to be flakey with our spiritual needs (scriptures, prayers, church attendance, etc.). We would rather miss dinner than to miss reading scriptures and praying as a family.
