From her blog:
I’m guessing what upset you most about the book was that you got no WARNING. There is no backmatter to inform readers that they might encounter diversity in this book. You may feel that your daughter should have had a chance to choose for herself that she was about to encounter a few lines of text in which there were gay people. I don’t know how this would work. Should I have also included a warning label: WARNING: THIS BOOK HAS SOME JEWS IN IT?
And as I haven't read the book yet, I just ILLed the hell out of it.
