this book is pretty good, it goes into a lot of detail about preparation ,personal fitness, bike setup, the rally itself etc.
lots of photos aswell.
a lot of effort went into the book , although calling it a book is a bit of a stretch, its more like a large magazine, or annual magazine (think enduro illustrated) and it is expensive.
nonetheless if your a true fan of the dakar and rally raids in general, you'll be happy enough with this purchase, it is rare that people put this information together for this sport, it's still pretty niche.
there are one or two other books of late that will be interesting to check out as this one was written about 2006.
