Don't forget that you can apply all kinds of elements from social influence, persuasion, obedience, etc., etc. to your analysis.
But here's some additional websites and readings more directly on cults/totalitarianism that might help with the book review:
Lots from Zimbardo - check the downloadable documents link. http://www.zimbardo.com/
Janja Lalich's website: various writings on cults: http://www.janjalalich.com
Ben Zablocki's site. He has run the only longitudinal study of cults (30 years now). Also has excellent articles on the academic controversy about cultic studies. http://www.rci.rutgers.edu/~zablocki/
Steven Kent has done interesting work, especially in relation to children - but also Scientology, and other things (navigate to different sections from left panel) :http://www.arts.ualberta.ca/~skent/scientology.html
Here's some downloadable documents we'll be reading soon, but are related to cults again (cults in the workplace):
