***Update***: As commenters have noted, the book is not available for pre-order in America… just in the UK. Yet another reason they are superior to us 🙂
…
Ariane Sherine is the brain behind the Atheist Bus Campaign, and her new book The Atheist’s Guide to Christmas is finally available for pre-order:

The book features (not coincidentally?) “42 atheist celebrities, comedians, scientists and writers” offering “funny and serious tips for enjoying the Christmas season.”
In case you need an incentive to order this one, all the money from the advance and royalties will go to the UK HIV charity Terrence Higgins Trust.
The book is available on October 1st, about a week after Richard Dawkins‘ new book comes out.
Talk about an early Christmas…
