I was disappointed in this book. While the cover clearly indicates the intended audience is between Intermediate and Advanced, I'd place it pretty close to Beginner. It is really geared toward the person who knows enough about VB to make some things work, but wants to refine his/her coding style. If you haven't learned this stuff by the time you reach Intermediate, you've probably already developed a lot of bad habits.
Also, the reference section just seemed to be filler. Why should a style guide have a keyword reference? It takes one third of the whole book. If I wanted a keyword reference, I would have bought one. What little valuable information he adds could have been done in 20 pages instead of 150+.
As long as you want a book that is geared closer to beginner than intermediate and you don't mind some fluff, then this book is okay.
