Here are two things that have changed since the publication of Pink in 2009: 1. I used to be a bit nervous about saying that, at the beginning of the book, Ava has a girlfriend. I got some disapproving looks from teachers, especially at religious schools. Students would giggle and whisper. One girl loudly informed me that it was "gross". Not anymore. Four years later, and nobody blinks. It's just part of the story. Nothing unusual. This is a really, really good thing.
2. Four years ago, when I held up Pink, boys would wince. And girls would say "I like that cover". Now, instead of mentioning the cover, boys and girls alike (but mostly girls) squeal IS THAT A QUOTE FROM JOHN GREEN ON THE COVER!???
And one thing that hasn't changed:
I get more fan mail about Pink than all my other books put together. I've received so many emails from people (young and old) who say that Ava's experiences spoke to them, and made them feel braver, or less alone, or prouder about being a nerd. And I'm so grateful for those emails, and so very glad that the book is reaching new readers, and that people are still enjoying it.
