This is not a photoshop for dummies book, but if you have got past the basics and want to move to higher levels then this book along with "real world color management" & "Photoshop 7 Color Correction" are worth buying. I gave these books high marks, I've read some really bad ones and some just plain re-hashed stuff but the above 3 are real "life changing". The writing style is fluent and readable. No gimics just the facts. I now understand why my prints don't look my monitor, why I need profiles and why I need colour management and what LAB space can do for me. Best of all I now know what questions to ask and how to understand the answers when searching on the internet.
