So, I read the book. It provides great insight into the mind of abusers. It's extremely helpful to be able to spot the signs of abuse.

Yet when I looked up the author I sadly found that he believes trans women are in not women, believs they shouldn't be allowed space in women's sheltes. It's hard to believe someone who claims to truly care for women's well being when they will deny assistant to some of the most vulnerable. I cannot separate this book from it's author's bigotry against trans women.
