I found this book very irresponsible. It's geared toward new marathon runners, and specifically new runners. Pushes 70+ mile weeks on a regular basis and poo-poos cross training unless it involves your running muscles. That's setting someone up for injury. Way too many miles for a new runner (and you better be running, no walk breaks allowed!) and the point of cross training is to keep everything balanced, not work muscles that see the majority of the work already. Move your body in different ways. There is a section on circuits, but it feels like it's tossed in because the author was told to, not because she wants to. It comes after she complains about cross training and weights.
She writes as though she expects a new marathoner to qualify for Boston.
The clothing, nutrition, sleeping, race day, injury care (no prevention, though) and race finder (although it's old) sections were decent, but not worth buying the book for. I would think most people who were going to buy this would do so for the training advice.
Unless you want to get hurt, skip it.
