I had such high hopes for this beautiful book. It could definitely function as a coffee table/art book, or (as I'm going to do) a collage resource. The first half is kinda fun and has lots of angel/demon names and types, so this could also be a good resource for worldbuilding etc. But this does not fix the juvenile writing and grammar mistakes or the eventual devolving into ancient alien-type conspiracy theories and long passages about Jungian patients and "multiple personality disorder." This does not have a bibliography and multiple times prints unsourced as fact what everything else I could find labels "fringe theory." And then there's the one paragraph that's very strange about Jewish people. Do not recommend unless you're a strictly pictures person.
