If you are looking for a book to guide you through the steps of taking great photographs and de-mystifying the more obscure settings on your camera, this is not the book.
It does have tips and pointers, and some nice shots to explain the text, but the strength of the book lies in the later chaptes on image editing.
The particular focus is on using photoshop elements, and it gives you everything you need to know to enhance and/or alter your digital images. If this is what you are after, add this to your library.
Once you've mastered 'elements' you may even want to splash out and buy elements big brother, photoshop.
