I have mixed feelings about this book. On the one hand, it does offer an extensive overview of djinn folklore and history. On the other hand, Philip J. Imbrogno has been exposed for having told untruths regarding his educational and scientific background and the science and “evidence” presented to make the case for the real life existence of djinn in this book is laughable and this is before taking into consideration the authors’ unified theory of all things paranormal being djinn. Expect not everything paranormal is caused by djinn, because fairies, aliens, demons, and everything else is quite possibly real as well. I can only think of two reasons why the authors would present such a wishy-washy theory. One, they want to write and continue to sale other books they have written about these other subjects and stating that all of it is djinn might present a problem for them. Or, two, they know their theory is crap.
Now, let me say a few words more about this “evidence” of theirs. Most of what is stated as facts about djinn comes from folklore and Islamic religious text. That’s fine, if you’re just using these texts and stories to give the reader a background on the history of the belief in djinn, but in several areas of the book it seemed that the logic being used was, “Well, if the Prophet Mohammed or some other old Muslim said it then it must be true and it must be djinn.” Mixed in with this were a few modern day accounts of djinn activity. Many of these accounts came second or third hand. Many of them were reports of activity given by people who themselves did not believe they were dealing with a djinn, but who the authors, for various reasons, believed were. Nearly all of them sounded like crackpots or liars.
Then there is the authors' personal experiences. Basically, they used the sort of equipment you’d seen on Ghost Hunters to talk to some djinn, who at first said they were demons but then after being asked again who they were said that they were djinn. Even if one is willing to believe that Guiley and Imbrogno were in direct contact with paranormal beings it’s pretty obvious they got the answer they wanted because it was the one they wanted.
This wasn’t the only area of the book where it was obvious they were stretching to find the answers and evidence they wanted. How far they were willing to go to connect everything that even remotely seemed paranormal to djinn can best be show in the title of one of the book’s sub-chapters, “Did H.P. Lovecraft Know the Djinn?” It was implied in this section of the book that Cthulhu was a djinn and that he, or maybe other djinn, inspired Lovecraft’s fiction. Cthulhu was a djinn? One can only hope that they were joking, but I fear not.
In closing, over all this book was a fun read, but shouldn’t be taken seriously.
