First off, let it be known that this is not a book you'll want to read unless, a) you are a huge fan of Arthur C. Clarke, or b) you are interested in such subjects as underwaters archaeology, shipwrecks, sunken treasure, etc. This book chronicles an expedition to the Great Basses Reef off the coast of Sri Lanka (then Ceylon) in the early 1960's, of which Arthur C. Clarke was a member. As it turns out, they came upon a sunken treasure ship, and recovered it. It was the first one ever found in the Indian Ocean, and, indeed, one of the few period in the last century. Clarke's writing, as always, is entertaining and witty, and keeps you reading, as the story is actually quite exciting (and has the added novelty of being true.) However, it does get quite dry and bland at times, as when Clarke devotes entire pages to legal esoteria and extracts from other people's writings and speeches. Obviously, it is not one of his major books, but neither is it meant to be. As a documentary, it is quite great. It reveals a major side of Clarke that many people are probably not even aware of. It also has many autobiographical ancedotes that fans will enjoy (it talks of when Clarke first felt the symptoms of his polio, for instance.) Also, there are over 100 great photographs in this book, including 16 pages of color ones. In the end, you will read this book if you are an Arthur C. Clarke fan, or if you are inherently interested in its subject matter. Otherwise, pick up Childhood's End.
