I loved this book - particularly the lighting sections, (which are the bulk of the book). The many illustrations are exceptionally well chosen to illustrate the effects in question, both from real life photos and from CGI rendering.
It really does not matter what software package you are using, the lighting is very similar in all packages I know, and the advice on where (and why) to place your spotlights, area lights and so forth is universal. Keeping rendering times down is also a continual concern in this book.
What is going on under the hood is also well explained, for those who are unsure of the difference between final gather and ambient occlusion.
I also really liked a computer training book where I did NOT have to sit in front a a screen typing to learn from it. Indeed many of the exercises involve looking around yourself for examples of soft shadows, indirect lighting, and many more.
Probably best for beginner to medium level graphics types, but I'd be surprised if anyone did not learn something useful from it.
Highly recommended.
