Reading this book 35 years after it was first born. This is one of the best and weirdest science fiction I ever read. There are places where you will have to read twice just to make sure you read correct eg. hyper-intelligent shade of the color blue or a planet where coincidence happens so much that people have left it.
English used is pretty simple and is easy to understand and there's are stickers which you can stick on your laptop etc. All in all a must read
