Well this sure looks like an interesting book:
There is no single methodology for creating the perfect product—but you can increase your odds. One of the best ways is to understand users’ reasons for doing things. Mental Models gives you the tools to help you grasp, and design for, those reasons. Adaptive Path co-founder Indi Young has written a roll-up-your-sleeves book for designers, managers, and anyone else interested in making design strategic, and successful.
And in an interesting twist I don’t think I’ve seen before, they have posted all the visuals onto a Flickr stream. At first I wasn’t sure if I’d order this book, but after looking at the sheer info porn that is included I’d buy it just for the visuals.
