Q: Reaching for the Light takes a very simple approach to a complex subject. Emilie Rose certainly researched ritual abuse well for having known about her own abuse for only one year prior to writing this book. In my opinion it takes years of therapy and intensive work to fully understand the damage done and the path to healing for the deep problems within. Any therapist who has worked with a ritual abuse victim for more than a year would not get anything from this book. Neither would anyone who has been in this hellhole beyond the initial discovery stage. My advice is to skip this book.
A:
Negative
