This book says it is intended for beginners only, so that's what it is for. It gives you a lot of info, tips, and things you need to know as a new person playing this game without overwhelming you with hundreds and hundreds of pages.
The layout of this book basically covers what you need to know from levels 1 - 10, after that, you will need to get another source of information.
I particularly enjoyed the detailed info on characters, spells, tips, the Jargon Glossary (which is very good so you can understand the many many abbreviations used in the game), commands , emotes, and detailed maps. Well, That means I particularly enjoyed the whole book then.
I recommend this book for someone who wants to learn, but not have a huge 300 - 400 page book to have to sort through. This book about 160 pages, very illustrated, and easy to understand. I am happy i bought it!
