Let me start with gripes: No Visible Bruises: What We Don’t Know About Domestic Violence Can Kill Us could have used a good editor to avoid repeats, organize the book better, and clean up some stylistic stuff. And the author, could have shown a wider spectrum of victims; she claims (and I believe her) that domestic violence cuts across gender and economic level, but we only see relatively poor women.
That said, she does a great job of showing why victims cannot leave, how law enforcement and social services strain at coordinating a proper response, and also how some batterers can change (with time, and great difficulty). If we made abating domestic violence a national (or international!) priority, we would undoubtedly see massive improvements.
