Comprehensive Overview of Most Religions and Cults
This book covers it all. If you are curious about world religions, cults or just the differences between Catholics and Protestants, "Why So Many Gods?" is a great resource. I used it with my high-school Sunday School class. At the end of the session, many asked where they could purchase the book.
It is written with teens in mind but is suitable for adults. Because of the sections on the occult, I would hesitate to introduce it to younger teens.
Although I appreciated the occasional snippet about how each religion differed from Christianity, the recap at the end of each chapter tended to come across a bit slanted.
