Homesite 4.5 is an excellant program, and some of its many features are quite intuitive. But you KNOW there is much more power under the hood... if only you could figure out how to tap it. This book succeeds in doing just that. It does a <<great>> job explaining, not only "To insert an image (for example) click here", but what the various image options are, how they will look, what options may not work with older browsers, and such. Nearly every page I read I thought to myself "Wow! Homesite does THAT?". A book has got to be REALLY good to accomplish that.
The review from LillySSS does point out one (potential) limitation: This book does not teach you how to create a web site. If you've never created a web site before, neither this book (or, in my opinion, Homesite itself) is for you. But if you've created a few pages with Frontpage and now need more control (or want to create pages that aren't so bloated with code) then this book should do the trick. Conversely, if you've hand coded web sites in HTML, the program and this book let you do exactly what you've been doing, but with a whole lot less effort.
In any case... if you are using Homesite, you will get a lot more out of the program, and become more proficient, with this book.
