This was an intriguing and quick read. The book opens up with an unsigned contract with the Devil and rest is composed in a typical diary fashion with side notes, doodles and clippings. It was quite comical at times and it was interesting seeing the "Devil's" spin on well known historic events. The only thing that got me is that it felt like I was reading the diary of a hormonal teen (who just so happened to control the underworld). It really made the Devil seem more like a child than the feared Evil One. Still, it's an entertaining book and worth picking up if you want a short and easy read!
