Query: confusing

The most confusing book i had ever tried to read. The characters and storyline changes with every turn of the page. It is hard to follow, and I've found myself going back several pages to remember the story of one or another of the characters. The only intriguing part was the ideas of the future and its enviroment.But its not worth the effort you put in just trying to read this damn thing.
