I just got my copy of this book and must say I am impressed - much better than I was even expecting. I am strongly recommending it as a present for anyone who has an interest in atheism/theism, from either side of the debate. OK I have a piece in it, but that's not why I am recommending it (I make not a penny from any sale). It's just a great read, from great authors...
