While the people that need this book the most are the least likely to read it, it may help those on the fence make up their minds, and give existing atheists and agnostics articulate counter-arguments to religious claims. Fans of Hitchens's acid wit won't be disappointed.

This book makes a good companion piece to Dawkins's "The God Delusion," covering the social and historical argument against religious belief while Dawkins handles the scientific and logical one.
