We just read (listened on cd to) The Last Book in the Universe. It was really good. I can't speak for my wife, but I can try. If she were writing this post she would say something like, "this book was one of the most refreshing books we have read in a long time and you should all read it!" Or something like that.
It is hard to explain what the book is all about without giving anything away or accidentally tarnishing your impression of the book before reading it. But I will say that it is kind of a cross between The Giver and City of Ember, but different. Does that help?
Either way, I will confirm the words that I think my wife would say about the book "you should all read it!"
You can take a look at it here.
