"United States Catholic Catechism for Adults"
The content is excellent.
The most distracting and annoying aspect of this book are the references. For example there are numerous parenthetical references to other works, bible passages and the like. All of these things are good and proper in the hard copy version, and the reader's eye can easily skip over them.
But the narrator reads all of this stuff, and it's very annoying. It would "read" much better without all those references.
