This book trys to give an upfront view, from the point of judeo/christian book reading. Most of the information is about "book" religions that dictate what to believe but does explain their religion well to those of the other religions. Suprisingly the native american religion was covered. They tried to limit their research to those of 1 million members or more. It would be good if they tried to expand this book into a series so everyone was covered , from their view ,so it is known what their view point is of the 'lesser' religions.The up front review of this book is to save the money.
