I managed to finish this book because the story is captivating, but the book definitely is not. The analysis is superficial, and Cayley clearly runs out of new things to say so she ends up repeating the same things over and over and over again. As one example, she mentions AT&T strong balance sheet (pre-Armstrong) a half dozen times, and even gets it wrong - on one page, she says AT&T long-term debt was $126 billion; elsewhere she says $12 billion. Her description of the personalities involved is likewise superficial and repetitive. She mentions Armstrongs "Big Blue way of looking at things" at least a dozen times (I am not exaggerating). There's even a entire discussion (regarding negotiations with Time Warner Cable) that is given in its entirety twice (pp. 189 and 190).
Another serious complaint is that the language of the book is inappropriately informal for the subject matter, even downright vulgar in a couple of places. Her very poor writing style just adds to the book's generally sloppy impression. This impression is not aided by the careless errors that pepper the book (e.g., referring to Microsoft as a cable giant). Didn't anybody edit this thing before it hit the shelves?
Most annoying of all is the approach of following parallel lines to that fateful summer of 2000, then backing up to follow another line of thought. It seems to be an attempt to highten the drama, but it fails miserably. A chronological order would have made the story much more interesting as well as making it much easier for the reader to figure out what went wrong with AT&T and perhaps learn something from the book. But perhpas this is just as well as Cauley's research would not have been up to this task.
I bought this book expecting some new insights, but there was nothing in here one wouldn't already know from reading the Wall Street Journal as the collapse was happening. Cauley simply did not do any homework or dig beneath the surface in the least. Overall, a very weak effort. I give it a low C or high D mark.
