I picked it up as the the back cover made it sound quite fun. I think I found this book because I was looking for fantasy books where the fantasy creatures are forced to interact with the modern world. Unfortunately, it didn't capitalize on its back cover premise.
The writing was honestly a bit dull, and our protagonist Bart was a bit of a Mary Sue.
This came off more like a "let me tell you about something I once heard" and less like an actual adventure story. I would have enjoyed it quite a bit more as a 45 minute short film than as a (admittedly thin) book.
