This book is temporarily free at Amazon Kindle. With such short notice I obviously have not had a chance to read it, but the basic premise sounds interesting, and it seems related to Arguing with Friends. Take a read and see what you think.
That’s a Great Question: What to Say When Your Faith Is Questioned
If you’re interested, here is the author’s Goodreads page. I didn’t see a website for the author, though I didn’t look very long. If somebody else finds it feel free to drop that in the comments. Also, any quick book reviews can be added there too.
