This book is a well-written factual account of a RN diver's experiences whilst completing the grueling course (which reminded me vividly of my own experiences as a SA Navy Diver), also during the Falkland War and his subsequent career as a commercial diver. It is full of amusing anecdotes as well as a few harrowing accounts, reflecting the authors steely nerve as well as his sharp wit. It makes for easy reading and will appeal not only to those who enjoy literature with a military flavour, but to anyone who enjoys a good non-fiction story.
