Maybe she's like comparing four different English translations of Art of War . . . along with commentary, it would be a good idea, just to get an idea of the implications . . . ;-)>
Isnt that the illustrated version? It might explain the extra pages. ;-)Or her ex sent her a page no. by phone to explain his strategic considerations in breaking up with her. Although I realise that a comprehensive explanation would be somewhat over the top.

That's first copy I found, before I knew much of the book, because it's the most prominently featured in most major bookstores. The author spends quite a while talking about ancient Chinese military practices, technologies, and campaigns that textures Sun Tzu's world. There's a helluva lot more than just the text.
