I was asked this question by a Christian who comments here at DC. I replied as follows:
It depends on your interest, and/or ignorance, so take a look at my book descriptions and see for yourself.
My challenge to you is to pick one, any one, and read through it. If you come to a book that does not tell you something significant you haven't considered before, then stop reading my books. But if each successive book does tell you something significant you haven't considered before, keep reading them until you're done with them all. If cost is a factor then get them at your local library.
Even if you should choose to read my co-written book, "God or Godless," because you want a Christian apologist to help you think through the issues, that won't help you! As Led Zeppelin sang, when the levee breaks "crying won't help you; praying won't do you no good." ;-)
You have no more excuses.
