Be aware that if you read Scuba Diving Magazine's "Lessons for Life", either on their website or in the hard copy, most of the accidents in the book are also covered there, although the book goes into a bit more detail.
I find both the magazine articles as well as the book to be interesting and informative reading, if not a testimonial to the never ending degree of human stupidity.
One accident in particular bothers me more than the rest..the one about the guy who urges his girlfriend to penetrate the wreck. He survives with minimal injuries, but she inexplicably dies inside the wreck, while he has plenty of breathing gas due to the assistance of the divemaster, who suffers lifelong paralysis as a result of his rescue attempts.
