The Shadow over Santa Susana by Adam Gorightly (2001)

I liked this book alot. I have read almost all the books witten about Manson and am an avid collector. I found Gorightly's book to be one of the best. It is full of the little facts that other authors seem afraid to print for whatever reasons. He delves deeply into the Hollywood scene, the Haight, all of the 60's rebellion, drugs, MKULTRA, it is a fascinating read.
