A moving and mostly fun and funny book about sisterhood, individuality, family, feminism, and, yes, style and grammar. As a copyeditor, I'm squarely in the target audience — the wordplay and the portrayal of descriptivist/prescriptivist views are part of the appeal throughout. If I started to get just a little glassy-eyed in the back half of the book where the driest grammar analysis lies, the humor and pathos of the relationships are what brought me back around again.
