If you're an atheist, you don't believe in the three wise men - so this Christmas, we bring you not three by 42 wise men and women, bearing gifts of comedy, science, philosophy, arts, storytelling and knowledge. Was there really a Christmas star? What does it feel like to be born on Christmas Day? And where can you listen to the echoes of the Big Bang on December 25th? The answers to all these questions and more can be found in The Atheist's Guide to Christmas.
