Of the books written about survivors of sexual abuse/incest (and I've read almost all of them over the past 25 or so years), Ken Graber's Ghosts in the Bedroom is the finest and clearest I know of for partners of incest survivors. It is concise and well organized, and it raises and addresses questions that those who love, or are in a relationship with, a survivor need answered. I recommend it highly to anyone in such a relationship and also to those men and woman who are themselves victims/survivors of sexual abuse and incest.
