I find this book a good plot despite some lengths. Sometimes a little confusing that certain terms or words used are supposed to be known by the reader and I happened to block certain passages. I had that impression because I do not know well the world of science fiction and I wanted to discover with this book, which is not necessarily the right choice for a novice player in SF. Isaac Asimov and Dick seemed to me more affordable. That said, I read the following account as the background story is very fascinating.
