This book certainly is good at delineating the effects of childhood abuse, ie the likely problems around self-esteem, sexuality, trust, anger; the potential issues about wanting to abuse power with children, addiction etc. You can hear yourself saying 'yes' after some paragraphs, however I would want to note a couple of words of warning.
1) It's very american. Nothing wrong with that, but if you are English, the whole thing can sometimes read a bit alien. As a nationality, we are more buttoned down and reserved, not just because of abuse we may have suffered and in an area like this, so personal, the tone can sometimes jar.
2) There is a chapter entitled 'Making Peace with your Abuser.' Do you really want to make peace with your abuser? I found this chapter naieve and it made me angry to read, partly, I'm sure, because I am very angry anyway, but also it felt misguided. Someone who has abused you as a child, particularly in a sexual way, is never someone you want to make peace with.
3) The final chapters talk about spirituality as part of healing. I think that is fine for those who subscribe to spirituality - in its broadest form - but if you don't, then it can feel like you are excluded if you do not subscribe to that world view.
For me, this book is a good starting point to examine the most painful issues, but, by the end, I was quite irritated by its naievety.
