Query: HORRIBLE BOOK

This has to be the absolute worst book that I have ever read. I have read about 20 or so Cisco books in the past year and a half, and I must say that this is the worst. Within the first 10 pages of chapter 2, the author states the exact same thing 3 different times. There is no organization to this book. I have to admit that this is a very technical book, but it doesn't break it down for you. Stay with Cisco Press and Syngress, they are about the best out there.
