This book is valuable for those Christians beginning to become world prayer intercessors. The book is topical, listing by countries. It is very easy to navigate. It provides good background information for each country and some specifics that aid in prayer. At the end of each section there are specific prayer requests that make praying more accurate. I would reccomend this book to anyone who wants to start being an intercessor in the world. Experienced intercessors would find this source valuable for general information. If experienced intercessors are looking for a good book to make their prayer more specific, I would try Praying Through the Window III: The Unreached Peoples.
