It is called Deliver This, by Marisa Cohen
It is not specifically or directly related to birth trauma, but it does mention it in a very fair way - and it doesn't really minimize it like a lot of books do. It spends several pages talking about it. It does have a quote from someone at the end to the effect that she and her baby were okay and that was most important, but I am not sure how else she could have ended the chapter on a positive note, other than to try to show someone who had gotten past it.
Anyway, the focus of the book is on all the different ways to have a baby, from home birth, to natural birth at hospitals, birth centers, epidurals, planned C-Sections, etc. And she provides some evidence and examples and both sides of each story to try to help the reader have the best chance to make the decision that is best for themselves. Which, since many people here and IRL diagree with for one reason or another, is very helpful to read.
I am part of the HBAT tribe, and I am committed to having a better experience this time no matter what. This book is helpful in that it describes points of view that I would otherwise not have been exposed to.
Just wanted to share...I know there will be other people who will not like this book, but maybe some of you will. I actually liked it better than Birthing from within.
Happy new year, yall.
