I found that it was very helpful in explaining the aftermath. But I also found that it wasn't graphic, like a lot, it didn't trigger flashbacks or panic attacks. It also has sections for friends and family, I know that my partner found it invaluable in learning how to support me and gave information on how to take care of himself at the same time. I have recommended it several people. I think that every survivor should have a copy.
Some parts are also very relevant to rape survivors.
Recommended by Cassandra. We didn't end up buying it as it is mainly about child abuse. I am sure that it probably would have been helpful, but at the time he was looking for something rape specific. Many people have recommended it as being the 'bible' for significant others. A comprehensive handbook for rape survivors and concerned family members, friends, and lovers presents an updated format covering health issues, incest, legal information, Post Traumatic Stress Disorder and more.
