Overall the book is great, but a long read topping at 601 pages. For me, the middle of the book was difficult, mostly where Garland wrote repeatedly about different ministries of the church and also different ways to survey (this is the only reason I did not give it 5 out of 5 really).
My only other qualm was that despite Garland speaking about singles and different types of families besides nuclear families, she primarily is writing considering these families, though I am not sure if she is even aware this comes to the surface. I get the feeling she tried to fight it and be as inclusive as she could with families, but I still felt singles, single-parents, and step-families were mostly neglected despite her attempts to do otherwise. She did include small sections, but considering 25-33% are single in the church and there is a divorce rate of about 50% it seems those should have had more attention in the book.
Finally, I think Garland could have covered this better by titling the book Community Ministry instead of Family Ministry. Overall great book with lots of information psychologically, sociologically, and theologically. I cant imagine how much work she did to write this book!
