The Satanic Bible, and The Devils Notebook. Both by Anton LaVey.
You may not convert but you will probably agree with alot of stuff he has to say. Theres a cool chapter in TDN called Lycanthropic Metamorphosis(spelling?) or some shit.
The Black Dahlia Avenger. By Steve Hodel. Great book. Non fiction. Actually its an amazing book.
Im sure I can think of some others but nothing else will compare to The Black Dahlia book. Plus the movies coming out soon so it will be cool to know the truth then see how bad the movie is. Once you start, you wont put the book down till youre done. If you do start reading it let me know what you think.
