I found this book in the library, and I just sort of stared at it for a second, before picking it up and borrowing it. This is an amazing futuristic novel, and I later borrowed Thunderhead and The Toll after reading this. This is my absolute favourite book, along with Thunderhead and The Toll.
I would give this book a 12 star-rating, but since that's not allowed, I 'll have to stick with 5.
I recommend ages of 12+ to read this book.
