Sinjin Smith seems to have a tendency to polarize volleyball people. They either love him or hate him, for the most part. No true volleyball lover, however, can deny his impact and influence on the beach game.
Kings of the Beach, though, is less about Sinjin than it is about the history and development of the beach game, with the occassional aside about the indoor version as well. If you are at all interested in the history of beach volleyball, you definitely want to read this book, and will almost certainly enjoy doing so.
