I was going to give this three stars, but it feels a lot like filler that could have been crammed into one of the main books. Plus, only 75% of this ebook was actual book. The other 25% was ad-space for one of the author's other books. Like, if you're going to charge me 99 cents for something that isn't even book length, is it too much to ask that it all be actual content? I don't think so. I'm deducting a star from Gryffindor for (un)intentional deception.
This was entertaining but I wouldn't recommend it. All you need to know is that you can never trust a demon. But hopefully you knew that already.
2 out of 5 stars
