A good book for Scientology?

I am looking for a book that goes over the beliefs and principles of Scientology. I just received Dianetics, I haven't read much of it yet...but does it go over the beliefs of being a Scientologist?
If it doesn't what book should I get?
This is a serious question, I am not looking to become a Scientologist but I love studying different beliefs.
Just looking for a good book going over what a Scientologist believes etc.

Just watch more south park

"The Road to Xenu"... read it on line for free.

Kingdom of the Cults should give you a biased overview.

PLEASE do NOT get sucked into that organization! It is a big big scam- to get your money. They make you pay and pay and pay- they are so screwed up, it's amazing.

Won't you PLEASE read up on Scientology?? PLEASE http://www.xenu.net/

Dianetics is a great start. Once you're done with that, Scientology: Fundamentals of Thought would be the book that covers the basics of Scientology.

Scientology: A New Slant on Life (easier read) or Fundamentals of Thought are both good books for the basics of Scientology. Dianetics and Scientology are two separate subjects.

There is a book called ' what is Scientology" By l Ron Hubbard.
