As a childbirth educator and doula, I can honestly say I enjoyed this book more than the full version.
Unlike the longer/full version, it is geared toward the regular people who want to support a birthing person in their lives, but who are not actual birth workers. It is detailed, yet to the point. It is a great manual for someone who wants to better understand birth in general and unmedicated birth specifically, as well as how to support it.
Plus, you get information about the most common routines and procedures in the hospital, what they are for, why they do them and how they are done. This super informative book is good enough to read alone without a childbirth class AND it is an excellent accompaniment to any childbirth education series you might be taking with your partner.
If you only want to read one book about labor and birth, try this. It won't disappoint.
