Look at MANKIND shoulder to shoulder with a book by Barbara Tuchman on the bookstore shelves.

Those of you who didn’t win a copy of Mankind: The Story of All of Us have a second chance. I’m blogging about Big Bang, Big Brains, Big History over at Wonders & Marvels today as part of the 12 Books of Christmas give-away. Leave a comment on the blog post over there to be included in the drawing for Mankind. (Comments left on this blog won’t count for the drawing.) While you’re there, check out the essays and books of my fellow contributors and comment on anything that takes your fancy. If you want an additional chance to win, sign up for the newsletter.

Book promotion will be over soon, I promise.
