Which book are you referring to? Are you referring to the book "Sun Certified Web Component Developer Study Companion" by Charles Lyons? Please specify.
Assuming you're talking about my book, I'd feel awkward telling you how good it is (because obviously I'm going to say it's great aren't I?!) If I'm to base such assessment on Amazon reviews, it gets an average of 4.5 stars. But you're best reading what other people have to say. I've linked lots of reviews in my post in the sticky thread.
