This book is phenomenal. It's a cool and original idea and is written excellently. It's one of those books that is almost adictive: you can't help but read one more chapter every time you decide to stop a reading session. As evidence of this, I was not initially planning to read the book when it first arrived, but I decided to have a look at the first page after opening the package it arrived in and just decided to put what I was reading before on hold and read this instead. It did drop off a bit towards the end, but that doesn't affect how great this book is much.
