This one sounds quite useful, looking at the layout of the book it reminds me of a good Cinema 4D book, I'm sure its worth it, read the reviews at the bottom;
Quote: "This is a book that gets straight to the point. It covers a wide variety of rendering topics relevant to vertex and pixel shader programming, all with clear example code. The topics are covered in enough detail for the reader to create their own great 3D effects. The introductory sections are well structured and serve as a valuable reference for HLSL and shader assembly. On top of all of this, the coverage of new shader models vs_3_0 and ps_3_0 is the best I've seen. Five stars! "

I'm sure if you're not in the UK, your amazon will have it, these sort of books are generally sold on most amazon sites.
