I don't have the book, but I saw it at my LYS. From what I can remember it had some very different patterns in it.
Coriolis for one is VERY different. Here's a free pattern for it when it was on DIY.
I found a bunch of the socks (various patterns from the book) being knit on Ravelry. Some of them look like they are constructed differently for sure. Maybe your library has the book?
