Let me start with the easy part and say that this is a very good book. I found it to be well written and very comprehensive in it's coverage of Warp. Twelve hundred pages may sound daunting but this book is well laid out and information can be located easily and quickly even if you don't read it cover to cover. Notes give definitions or explanations of topics that might not be immediately obvious. Tips are used to show how things could be done in different ways and perhaps make things easier.
Warnings are fairly self-explanatory.
The Instant Expert sections contain some of the more interesting information. Each section is well laid out and the overall flow of the book is very good. The definitions here are clear and easily understood. I did find two small items that were incorrect but these are obviously a result of changes made after the book went to press. Either way, this is a great book and well worth the investment.
