To be honest, it would be dry reading if you attempt to read the book in one or two sittings. To use the book more effectively, you would either read it for research, or as daily devotion. Many of the stories are about 4 to 7 pages in length -- makes the articles quite readable for daily reading.
I should also point out an interesting chapter. There is a chapter on "a Chinese Christian" -- an anonymous person in the house church movement in China. A no-name, "ordinary" Christian who practices his faith but remain anonymous because of the fear of persecution, the story reminds me of millions of other Christians in the worldwide Church who are persecuted. Good inclusion!
