Katherine Paterson has been named to replace Jon Scieszka as the national ambassador for young people's literature. Best known as the author of Bridge to Terabithia, Paterson's parents were missionaries and she spent her childhood in China finding friends inside books. Here's a quote from her from a NY Times article:
"When people say, 'Don't you want to write for adults?' I think, why would I want to write a book that would be remaindered in six weeks?" Ms. Paterson said. "My books have gone on and on, and my readers, if they love the book, they will read it and reread it. I have the best readers in the world."
