Leaving aside the fact that Reading Rainbow is no longer in production, what do you think? Even the blogger says he loved Stitches. But it is true that it was published an adult book.
I haven't read it yet. I read Maus years ago, have a copy of Fun Home that I keep meaning to read, and just bought a copy of The Impostor's Daughter after meeting the author at Wordstock.
One thing's for sure: all the controversy is going to get a lot more people talking about Stitches than if the publisher had just nominated it in the adult non-fiction category. [Full disclosure: do you think they knew that when they did it?]
