Of course, this isn't an in-depth study of Islam... But for introducing concepts, etc. to a Christian audience, this pocket guide is INVALUABLE!
I picked up Bruce & Stan's Pocket Guide to Islam to see if it would be useful for a class I was teaching at church. This is the first book by Bruce & Stan that I have read, so I was not sure what to expect. Their book is well organized, but the content rarely seemed to get beyond the surface of the topics they approach.
I have read several books that compare and contrast Islam with Christianity from the Christian perspective. This one is my least favorite. It comes from a pair of academics (they studied about Islam following 9/11 and wrote a book about it). This being true, their comments on further reading (called "digging deeper") suggest some good reads. However, they plug their other books more frequently than I found necessary... <
Bruce & Stan have written clearly, but not deeply. Depth is what I was looking for...
