Great author? Satanist? You decide! Actually, I haven't read his series "His Dark Materials" yet, but I heard they were great. It is a "childrens series" but eventually they get into some deep religous stuff. I think he thinks since religion is an establishment, it is evil. He says all establishments are a form of control or something like that. But he says there is a God, but he is with the establishment. Anyways, just read it so we can talk . The books are (I think)
1) The Golden Compass
2) The Subtle Knife
3) The Amber Spyglass (I heard that in this one mass sketchy shit happens)
