I think this is the first book based on Blender's radical user-interface overhaul, so I decided it was a must-buy.
For the confused, the title is a bit misleading. Blender 2.6 is a long way off, and even 2.55 is currently available only as a beta version. This means that occasionally the book refers to an as-yet unavailable feature or hot-key.
As you would expect from this established Blender author (and nice guy!), his book is very, very good. Not only does it cover a vast amount of what Blender can do, but at various points it also gives you a heads-up on related matters that it DOESN'T cover.
Chapters include:
The interface
Animation basics
Modelling a scene
Lighting
Modelling and rigging a character (including hair)
Adding textures
Using the 'sculpt' tool
Shape keys and morphing
Rendering
And stuff like cloth, force fields, soft bodies, particles, etc.
And a final chapter on Video compilation and final output.
It's a great book, and only a few things prevented me from giving it a 5-star review. The MAIN one is that when I buy a book, I prefer it to be 'stand alone'. If someone new to Blender picks up this book, they have NO CHANCE at all of making sense of it unless they're prepared to frequently visit the associated website. The book doesn't give nearly enough step-by-step illustrations - instead, it tells you that you'll find them on the website, together with various other videos etc. (which I admit, are all very good - but I would have preferred them on a DVD, making the book a 'complete' product.)
Maybe this is just a personal thing - if it doesn't bother you, then consider this a four-and-a-half star review. The missing half-star is because of some fairly serious errata (which, again, is put right on the website... mostly.)
Despite these reservations, I recommend the book very much. If you're uncertain whether or not to purchase, why not visit the website in advance? (blenderfoundationsDOTcom)
