Caveat: I started reading this several years ago, when I was struggling with a PTSD diagnosis and very active symptoms. While the author addresses trauma in general, childhood abuse -- especially childhood sexual abuse -- is a focus. I found it helpful (though disheartening for a while) to read the author's insights on why this is perhaps the most deeply affecting type of trauma. It did help me move beyond my rejection of the diagnosis ("PTSD is something that happens to people who went to war"). It helped me realize, childhood abuse is like going to war, living in a war zone, being a prisoner of war.
I also found the distinction the author makes between intrusive memories and flashbacks to be really helpful. No one had ever explained this to me, and I think many lay people (and even patients/survivors) are made to think of flashbacks as unexpected, unwanted memories or mental images. The author categorizes those as "intrusive memories," which can occur within flashbacks or outside of them. Flashbacks, on the other hand, feel like that unwanted memory is actually happening right now. They pull you out of your current reality into an active reliving of traumatic events. This book helped me understand that having very visceral body experiences during flashbacks was, while unpleasant, normal. It didn't help them stop, but it did lessen the worry that I must be going crazy or that my experience was unique (since providers never distinguished this). It also helped me to come up with better language to explain the experience and get the help I needed.
-1 star because the information in the text is dated in some ways. I think a more contemporary text would include additional treatment recommendations and potentially could mention epigenetics. However, for a book that's 20+ years old, it still was well worth reading.
