William Lane Craig and Chad Meister are the editors of and contributors to the new book God is Great, God is Good, which is a response to the New Atheists.  I have not read the book yet, but I have read a review of its contents that makes me think this is one of the best books to-date on this subject.  Not only can it boast of the contributions of top-notch scholars such as J.P. Moreland, Alister McGrath, Scot McKnight,  and Gary Habermas, but it covers a breadth of issues raised by the New Atheists.  If you are looking for a concise introduction and response to the new atheism, I would recommend this book.  It was also named best apologetics book by Christianity Today.
