The followup to the debut novel Scott Westerfeld called "A spell-binding story about loss, rebirth, and finding out who we really are inside...intense and moving."

Months have passed, and in that time, Lia has joined Jude and his roving gang of mechs, an eclectic collection of bored teenagers looking for trouble, and uniquely capable of finding it. It's a carefree life at first, but as the download process becomes more common, the opposition to the process becomes more vocal - and more hostile.

Lia gets swept up in the idea of being a revolutionary and fighting for a cause, but as the plans escalate, she starts having second thoughts - especially when she figures out Jude's real agenda. Yes, he's loyal to his cause - fiercely, desperately, blindly loyal. But only to his cause. Not necessarily to his people. In the end, Lia must make a choice. How many people - mechanical and organic - is she willing to hurt to protect her freedom? How far is she willing to go to protect the people she loves? And, when she betrays Jude - as she eventually realizes she must - how will he take his revenge?
