The Magic of Reality: How We Know What's Really True Richard Dawkins' latest book that answers a large number of questions about science. It's an especially great gift for teens and preteens as it is fun and easy to read, with lots of illustrations.
God, No!: Signs You May Already Be an Atheist and Other Magical Tales Penn Jilette, the louder half of Penn and Teller, writes a fun and raunchy collection of stories from his life about sex, atheism, and more.
Atheism and Naturalism My book which makes an excellent introduction to atheist thought.
You should download my book Selected Essays. It'll make great reading during all your downtime during the winter. As I've described it:
"Think of the book like a deluxe DVD edition of this blog. It's packed with never-before-seen writings, and what you saw before has often been transformed.
"There's a fun skeptical chapter on why alien theories for the creation of humans, life, and the pyramids are bogus (besides common sense, there are a lot of fun scientific and historical facts that prove it is baloney!). There's a very original and fresh take on the fine-tuning argument. And in the last chapter of the book I show how a song by Jack Black disproves one of the arguments for God's existence!"
And if you need something to watch this holiday season:
Penn & Teller Bullshit: Eighth Season
Christmas with a Capital C Buy a used copy. It's an anti-atheist Christmas movie. It should be good for a laugh.
