Yes, it is definitely a great addition to your Satanic library. I bought it and practically had it read within 2 days, and that is a testament to its content because I have ADD and Dyslexia, so reading is a challenge and 1/2 with my eyes darting all over the pages. This book kept me focused and interested in the content throughout the entire reading of the book.
The Satanic Scriptures is an easy read, very informative, and very in-touch with today's Satanic generation and way of thinking. I highly recommend it, especially if you have "The Satanic Rituals" and "The Satanic Bible". Those 3 books are highly valued in my library.
