A+ for Ship Breaker
Great worldbuilding that makes you think about current affairs? Check. A setting that postulates a possible (bleak) future of mankind? Check. A great main character who is easy to root for? Check. Expressive writing with a complex, fast-paced plot? Check. Honestly, this book has it all. I might even have liked it more than I liked his adult novel 'The Windup Girl.' This is everything that a good SF YA novel should be.
Better than: The Hunger Games, Graceling, Incarceron.
Please read the first chapter and know that it only gets better from there. Highly recommended.
