Deity's Syndrome: "Multisystemic symptoms resulting from a psychosomatic manifestation of the unshakable fear that the patient is a character in a novel".
That mouthful of psychological jargon is the diagnosis for the character of Ideal Deity in Robert T. Jeschonek's My Favorite Band Does Not Exist. It also sets the stage for a wild allegorical ride through philosophical thought from the Greeks to modern Western philosophy.
Jeschonek does a great job of matching the actual format of the book to the story. You know when you are reading the book within the book because, well it's a book within the book! The language and concepts are accessible; this is not a philosophy text full of 6 syllable words. As the novel moves towards its closing, the story does gather speed, flipping through reality like a deck of cards in Alice in Wonderland, and it can be a little hard for the reader to keep up.
The question in the back of my mind throughout this fast-moving book was, "Would a teenager like this?" The book is targeted to ages 12 and up (grades 7+), and some of the vocabulary and plot twists are more appropriate for the higher end of that range. I can see this being used in an English classroom to teach metaphors and symbolism; motivated students would have a field day deciphering names and finding hidden symbology. But would they read it for fun? I'm just not sure. I definitely know some kids who would love this - and some who would glaze over a few pages into it.
That being said, if you know a young adult that likes a story with a little more story to it, and enjoys sci-fi/fantasy, I heartily recommend My Favorite Band.
