The popular-level version of The Unseen Realm by Michael Heiser, which I reviewed early. Much shorter, less footnoting, simpler reading, more straightforward, but covers pretty much all the same material about the supernatural world from a Christian perspective. Answers a lot of questions about passages that were hard to fit in and raises a lot of questions about what is really going on in that realm. As this book is easier to take it or leave it and is designed for the broader audience, I recommend it for anyone interested in understand the supernatural realm without getting into speculative nonsense. Good book, good read, thought-provoking.
