I heard about this book two years ago when it first came out, but wasn't interested as I didn't see how you could fill a whole book about two divers exploring a single submarine. Things remained so, until a few months ago my Amazon order was a little light, and I figured what the hell, let's take a chance on it.

The good news is that my intuitition was correct: you can't fill a book with just the diving stuff. The bad news is that to disguise that fact, Kurson spends a lot of pages on filler material that has nothing to do with the subject.

Another problem with the book is Kurson's writing, which is embarrassingly bad in places. He uses asinine metaphors, embellishes facts, and adds drama where none is needed.

Many Internet sources claim the book is full of errors but for some reason these sources never list the errors, so I wasn't able to judge whether these claims are true or not. I wouldn't be entirely surprised if Kurson had taken some liberties with his story, however.

One good thing about the book is that the accuracy of the diving stuff is exemplary. I didn't notice a single error (well, maybe trimix wasn't quite as new as he claims, but it certainly wasn't mainstream), and he also didn't waste too much time trying to explain things to the general populace, which would have been futile in any case.
