Query: Disappointing

Poorly organized content as well as scarce and bland illustrations make this book not worth its money. In addition to following a totally unintuitive and strange organization, the information presented is superficial and, if I had to guess, 20 years outdated in many places. Also, the authors completely dropped the ball on providing references in the text, an oversight that is inexcusable in such a dynamic and ever-changing field as dive medicine. The only reason I gave two instead of one stars is that the chapters do include real-world examples of the material covered, mostly in the form of diving incidents and accidents. However, when I wanted to learn the latest and greatest about nitrogen narcosis, for example, the entry on wikipedia turned out to far outperform the chapter in this book. Personally, I would not buy this book again and don't recommend it.
