I'm not sure what to say about this book.
I didn't like Titus, the main character. I didn't like the world, I didn't like the constant advertisements. I didn't like the people. I didn't like that no one took Violet seriously.
But this is a good book. It's a scary book - a realistic commentary on American society that should scare the dickens out of everyone who reads it. It's like your Google account on steroids.
This is true, good science fiction. I should probably rate it higher for what it is and what it says. I just didn't like anything else about it - hard to enjoy spoiled college students acting like jerks and being so self-centered.
