Although Dan Brown's and J. K. Rowlings' books sell well, another volume, many centuries older, has them both beat — and its lead is formidable. The Bible, in all its editions and translations, is a perennial bestseller. (In the last 200 years, billions of copies have been sold). Karen Armstrong, one of the most eminent and thoughtful scholars of religion alive, will join us in the second hour, to talk about her new "biography" of the Bible. She'll take us through its books and testaments, provide important history and context, and outline past and contemporary debates over its veracity. What questions do you have for her?
