I found this book by accident on Audible and decided to download it, since it was only a few dollars. It's also a very quick read; it has only 88 pages to go through. 
 I hear there's a second, longer book, but I'm not sure it I'm going to read it, because this one didn't really convince me. 
 The idea of multiple personalities living in someones head and thus making him exceptionally smart is a great and interesting one. But I found the execution of this idea a little disappointing. We only meet a few characters and learn only so much about the protagonist, but it all happens too fast and feels too rushed that it made me want more. I feel like the author wanted to give his readers an amuse bouche followed by the second book which reveals more of the plot. But it was a little sloppy and didn't feel like a treat to me. Rather like a salad. 
 But it wasn't bad either. So maybe I will try the second book. Maybe.
