Don't ever order a pre-release. I ordered this digital copy on 8/24/22 (yes 2022) and it still isn't released.

The material is spectacular and the reading style is good. In a small group study the way the material is accessed in the audio version of the book can be confusing when using it alongside the book. The written book has 10 chapters and the audio book has 18 Episodes. It would be nice to title the audio book episodes so that they correlate with the book easier. Rating of the material is a 5, ease of use for a class I would rate this a frustrating 2. Just buy the book and pass on the this audio version.
