The New York Times has another story on The Higher Power of Lucky. According to the article, it all started when librarian Dana Nilsson posted a complaint on the LM-Net listserv. A passage I found amusing:
The book was in the high 600s on Amazon before Nilsson’s comments were publicized, but soon jumped into the top 40. Simon & Schuster had already ordered an extra 100,000 copies after the Newbery was announced.
