** spoiler alert ** 
 Written by an expert in essotoric religions, this book basicaly says that the Masonic Myth is that there are secrets. When they are no real secrets and no conspiracies. But then the author is a Mason, so maybe that's what the Masons want you to think! 
 slightly more serious: this is probably one of the best and easiest to read books on Masonic history and traditions. Just don't expect to learn all the mysteries of the world.
