Honestly, really very expensive for what it is.
The book builds up excellently from the beginning, for sure, and so gives the layman a very well structured introduction building from first principles. The book is also obviously written by some of the most authoritative guys in the subject. The remainder of the book becomes very dense though, dealing in slightly disjointed areas of intellegience (or not expressing the connections well enough for me to grasp them), using case studies from quite a long time ago now.
I'm not a subject matter expert so I couldn't recommend a better text, but I'm sure one can buy a basic introduction, and an up to date book of case studies, for less than the cost of this one book.
