This is a commercial read (less emphasis on plot devices and cramming as many words as possible into a single sentence), and it's meant for MG/YA. It flows easily although its jumps around a bit at times, but it makes it work. The Guide's definitions may throw a reader for a loop, because they are wild and wacky, but they serve a purpose in their fanaticism.
I really enjoyed this book. It was a fun and easy read and it took me less than four hours. It was witty and sarcastic and I've never laughed out loud so much while reading a book.
