This was a neat little read on the basic questions of whether it makes any sense at all to believe in God. I confess I was drawn to it in significant part because it was short, and I've been reading a lot less these days than I used to. But that's one of the pluses of this book. Amy Orr-Ewing does a good job presenting complex philosophical arguments in bite-sized, easily understood pieces. She makes some great arguments and exposes the often large logical holes in the popular arguments against belief in God. The short nature of the book is also its biggest weakness. I suspect that a well-educated skeptic might have a hard time buying all the arguments made here because they aren't argued in thorough detail. It would be easy to respond to one of her arguments by saying, "Well, that's a very good answer, but what about this other aspect?" Also, this might not be the best book for someone who has little familiarity with the questions discussed since Orr-Ewing devotes so little space to explaining the reasoning behind the questions.
So I'm not sure who this book is best for: perhaps the open-minded skeptic, and the Christian who has already done some reading on these questions. I wouldn't give it to a fierce, philosophical opponent to Christianity, or to anyone who isn't already at least a little into apologetics.
