This book focuses on the major urban centers in the 10/40 window. The background and statistical informaton for each city (including unreached peoples) is laid out in easy to read format. A map is also provied for each city and can help one keep the city in perspective. Specific prayer requests are listed for each city. I have found this book to be an excellent companion book to Praying Through the Window III: The Unreached Peoples. Using these books in tandem will not only make your prayer life more focused, but will also give you a deeper appreciation for other peoples around the world.
