Unless you're one of the lucky people with a brain like a computer, able to instantly bring to mind, that perfect reposte, during any discussion on religion or theology, then this is the book for you. Within it's pages, is a deconstruction of biblical and koranic arguments, added to scientific logic and a dollop of plain old common sense.
In short, it contains all the quotations and arguments an atheist might ever need, to win the inevitable arguments, in which we find ourselves so often. On top of that, it's contributors are witty, brilliant and mostly very readable. For those believers of one persuasion or another, who wish to confront the atheist argument; stay away from this book, unless you're ready to face the truth.
Good old Hitchens, his selection of writings is perfect, as we've come to expect.
