By far the worst dystopian world ever. If you are light enough you can be on Light Crew and if you are heavy enough You can be Heavy Crew but if not then too bad for you. If you are lucky you can find other work but kids in the book are out of luck if they don't fit into either category.

This book was really good and kept me up late at night to find out what was going to happen next. It is unpredictable you don't know if any of the characters will survive.

I recommend this to any dystopian/science fiction lovers. The second book is even better than the first but they are both really good!
