Query: Good but not great

This book has some good stuff in it, don't get me wrong. I think one of the problems with the book is it tries to fit too much information in a small amount of space. My biggest problems with this book is he makes some blatant errors when it comes to the topic of history and some minor errors in the mythology, especially the Egyptian mythos. I think the author really needs to go back and hit the history books to make sure his timelines and histories are correct, which as the book stands now, they are not. The other major issue I have is his section on Psychic Vampires, it is WAY OFF!!!! Real psychic vampires are not clingy, soul sucking monsters like he describes. I hope he puts this book back out with changes to his errors and readsThe Psychic Vampire Codex: A Manual of Magick and Energy Workand fixes those horrific errors regarding psychic vampires.
