Vox Day’s “The Irrational Atheist†is a comprehensive refutation of the most common “New Atheist†arguments and talking points. It is available here (http://www.voxday.net/mart/TIA_free.pdf) in .pdf format completely for free.
Also as a warning, Vox’s writing style is blunt and to the point. One may be offended (Christian and non-Christian alike) by certain words and metaphors he uses but the facts remain the same.
The book covers things like prison populations and the causes of wars, among other things. Keep in mind that this book was not written as a defense of Christianity or as an evangelical tool. It is only a refutation of common Atheist talking points.
